You can put those firmware files on the tftp folder and then put just the file name on the PnP page (no path required). After saving this page, just reboot the phone.
In the tftp folder I put a file called snom370.bin In the PNP settings under the firmare settings for this phone i put the same file name of snom370.bin However the phone fail to pick it up. I have no other tftp service running on this machine and the phone do pull down thier configs properly. Any ideas?

I just upgraded a customer this morning from 3.2 to the newest release of 4.2 on the website. The phones have firmware 7.3.23. I can make inbound and outbound calls however I can't make extension to extension calls. PLease help!

Hello all. As you can guess I have a network with no INTERNET access. So I have the new firmware for the snom phone on my PBX. I know I could start IIS on this windows box and point the pbx to that to get the updates. But I was hoping that I could just put it in the HTML or tftp directory. Has anyone done this and what would the firmware path look like in the PnP settings. Thanks for the help!

Hello all. I have a user who has 2 different greetings for her mailbox. They are running an old 3.2 version. Is there a way to delete all of her greetings and just let her start over? I know you can in version 4.x but I don't see and easy way to do it in 3.2. She is at a remote site but I do have access to the servers.
Thanks

Ye4ah I looked at those with not much success. I have to PBX packup from the Windows box and I moved it to /usr/local/pbx on the CentOS box. I have removed the old windows controler and placed the Linux controller in its place. So now all I need to do is get the service to start which is where I am falling short.

Hello all. We have decided to move our PBX from a Vitualized Windows server to a dedicated Linux box running Centos5. I have the CentOs install completed and I have the pbx working directory from Windows. Can some one give me quick directions how to make this work. I know I need to copy the directory to Linux and download the new controller for Linux, which I have done. I just need a little help with were to put the directory and any permission modifications that will need to be done. I am familar with Linux, I am just not a pro. :-)
Thanks in advance.

shouldn't you be clicking "g711" and clicking add?
I was able to get the codec locked at g711u and I am still having packet loss. Any other ideas? I am taking a beating here.
-
Matt, I thought about that and checked it. Here is my config. I believe this locks it but obviosly it does not.

On thing I have noticed is that on the trunk between PBXnSIP and Callcentric the are using G729A and we want G711u because the audio quality is better and we have the bandwidth. We have a dedicated 3 meg pipe for the pbx. Could this be part of my problem? And how do I get the trunk between Callcentric and the PBX to stay at G711u? Let's hope this is a step in the right direction.

Tom,
Want our team to give a crack at it?
I doubt it is an inherently Windows issue.
But:
-any virtualization going on?
-any chance switch is finicky?
-are the 10 people coming into the conference call on LAN phones?
-are the ext. to ext. calls that are breakin up on same lan?
just some ideas to get you going in the meantime.
Matt
Matt,
here are some of the issues I have found. We do have issues with ext to ext calls on the same lan. When the conference calls happen they are not always on the lan. Some dial in from outside sources. This is a virtualized server with plenty of juice to run pbxnsip. The switches are new linksys by cisco switches. I know Cisco switches would have been better but we needed 8 and I could not get the company to swallow that bill. I have looked at the CPU usage and it is very very low. I do have some low MOS scores so I know the PBX knows the quality is bad. So I am now running wireshark captures on both interfaces and sending them to a shared drive. I spend about 6 hours a day in wireshark.I have made one change to the pbx since Monday and that has been to increase the ram from 2 gigs to 4 gigs.
Any thoughts?
Thank you!

I have used both of these troubleshooting guides with no luck. The audio dropping happens everyday in all configurations. It happens on an extension to extension call, on a Callcentric to extension call. I have to figure out what is going on before people get more upset. I am thinking about moving the PBX from Windows to Linux as I have exhausted other options. I do have a support ticket open but have not heard anything back for 2 days. :-(

Currently, the conference recordings are not exposed to the web interface of the conference. You can look at the file system ('recordings' folder) and view the file. There was also an option to see/play the recording on the user portal of the conference organizer.
I have noticed a few things with this. If you watch the recording folder during the call it will show ther file as ConfXXXX.wav after the call is done it changes the file name to msgxxxxx.wav. Why is this? and is there a max size to the recording? My boss was on a call and had recorded it and now can't find it. I am looking in the recordingts folder and I do not see it. It was approx 2 hours long. We are using them same version.

Hello All. I am looking for some help with an on going audio issue that we are having here at out office. We are currently running PBXnSIP 4.2.0.3958 (Win32. We have a dedicated server that has 2 network connections. One is connected directly to the Internet via a 3meg dedicated fiber pipe. The second connection connects to a Ethernet switch. All of my phones plug into the same switch. The entire PBX is on its own network. Yet still I get audio loss. I am not talking about 1 way audio. Let me give an example. Last week I have 10 people in the conference room at out office who are dialed into a PBX conference extension via a single pod phone. I then have 4 folks from our Denver office dial into the same conference room. They are calling into the Auto Attendant like any normal person would do. During the meeting while the new Director of Operations is speaking the sound cuts out or becomes distorted. It is her voice that no one can here for a few seconds and then the sound comes back. This is happening more and more often. It happens in all types of situations this is just a single example. I had previously gathered some wireshark captures and I could see the audio was breaking up leaving the PBX to the phones but I am sure this is not the only case. Can someone please give me some assistance. I have already read all the stuff in the old wiki and most of it does not apply to our setup. One last thing. Our provider is Callcentric. Thank you for your time.

SOrry for the late reply. I was off the 11th and 12th last week. We are running version 4.2.0.3958 (Win32).

Anything from the service manager? If the PBX initiates the restart, it does restart the whole system...

Luckily this has only happened once. :-)Any thoughts?

You can use this as a checklist: http://kiwi.pbxnsip.com/index.php/One-way_Audio. For example, we had a similar case where the problem was a IP address conflict.
I have tried all of those recommendations already. :-) One thing that I am currently looking into in the speaker phone on the Snome phone. It appears that all reports of clipping audio appear to be on calls in which the speaker phone is being used. It is not an issue of one way audio per se because it just drops for a second or 2 in the middle of a 60 minute conversation or words will break up for 4-5 seconds and then it is fine. Any idea of changes that could be made on the speaker phone?

Hello all this is a relatively new problem we have experienced. I am getting small portions of audio clipping or a toal loss of audio (2 to 3 secopnds) in one way. I have done days of research on this issue. We are running G.711U I have a dedicated 3 meg pipe on the outside for the pbx. The inside interface on the pbx is on the dmz and all of the phones connecte to the dmz switch. So from the PBX to the phones it is 100meg switched network on its own vlan. I have wireshark running on both interfaces and I can see in the audio stream that the issue is occuring from the pbx to my phone! I have a hard time understanding why but it is. The streams in and out of the pbx to the provider(callcentric) appear to be fine. Does anyone have any idea where I can start to chase this? I have noticed that it does not seem to matter if the pbx is under heavy load or not it seems to be a random issue. Any advice would be helpful.

In Linux, you can check the syslog for admin login and other important events from the PBX. Also, if you ahve email notifications turned on you should get an email if someone requests a restart.
This is on a Windows box so there is no syslog server. I do have email notification on but it just told me the service was restrarted but not who issued the request. Maybe in a future version?

Does anyone know if version 4 is capable of running on a virtual server? Has anyone done this with success?
I run version 4 on a Hyper V virtual machine. It has been there for a year or so, starting with version 3.2 No problems at all.

Hello all, has anyone ever had the PBX service restart on its own? Mine just did it this morning at 11:30. How can I tell who requested the restart? Thank you.

Not using the SIP IP Replacement List is a good thing.
Did you set the outbound proxy in the trunk? I guess so. Maybe you need to tell the ASA now that it really can trust the PBX and there is no need to filter the traffic...
For the cisco ASA you need to make it sip aware. Just having a por tope is not going to help fro the out side. Here is a link to the 3 lines you need to add to the config. First set a global policy map then tell it to inspec sip. Yopu can trouble shoot more after.

Happy firewalling.

Hello all. I have a client that has exchange 2007 and PBXnSIP 3.4.0.3201 (Win32). Before we went to exchange for voicemail you could dial the direct dial voicemail number of 8 + Extension # and it went to voicemail I removed that for exchange and put 99$u in the external voicemail setting. However if I have someone try to send me directly to exchange voicemail I get a wierd error message telling me that I can not use that extension to make the call. ANy ideas how to achieve direct dial voicemail in Exchange?
Thank you!

Whow! IMHO you dont have to blacklist too long as the total impact to the system performance is really getting very low if you blacklist for something like 7 days.
Anyway. The dropdown just contains some useful (as we thought) proposals, you can edit the page in the admin/email/texts section and add another option for example for 365 days or longer.
Whewre do you endit the length of time? I looked in the above mentioned section and I don't see where I can edit that. Should it not just be one of the xml pages in the PBX directory that I edit?
Tom
-
No, no. The blacklisting uses some nice efficient data structures internally. The performance impact of even long lists should be okay.
You can also blacklist everything by default (0.0.0.0/0) and only whitelist certain IP addresses or subnets. If you know the IP addresses of your users/customers than that is a real option where you dont have to worry about people scanning your PBX.
In this case you also need to whitelist your trunk provider. The black/whitelisting does not support DNS, you you need to look the IP addresses where the service provider might come from.
Ok are SP is callcentric. Do you happen to know those? Thanks guys!

Firmware update for phones with no INTERNET
in General Setup
Posted
OK I have attached the pcap of the communication between the phone and the server during the phone boot. I have in the PnP firware settings only snom370.bin and it is placed in the html directory in the pbx folder. I have even deleted the generated file for this extention in hopes it would rebuild it, and it does but the firmware is still not updated. Thank you for the help.
