Vodia PBX

Did you see the speaker symbol in the web interface (when you log in as user and check the mailbox)? There you can download the WAV. Downloading even marks the message as saved!

We asked the chip vendor for an update, but so far nothing. The biggest problem is the threading library, which cannot deal with threads in different priority queues. We currently have a workaround that could come from the good old Windows 3.1 times, but that eats a lot of CPU power. The other issue is that it would be nice to have a "IPv6Ready" certified kernel. The software is "ready", but the OS also needs to be ready.

"It depends". For a 10-user installation how have to deal with maybe 40 MB, for 100 users it can go into the 100-200 MB. The number of calls also does matter. Fortunately, memory is cheap these days and usually not a problem.

Smells like a DNS problem to me... Maybe you can use the IP address in the outbound proxy instead to see if that is the problem. Keep the DNS name in the domain, so that Exchange does not complain.

IMHO MPLS is perfect for running the PBX in hosted mode for small companies. I would like to know if there is any experience out there with this.

Can you try it out? We can make a test build for CentOS.

It looks like we have a race condition here. When a message is being recorded it takes some time (ms) until the file made it to the file system. If the check if the file is in the file system is quicker than the file system write, the PBX might really think that there files is not there and it will delete the message. Workaround: Hard to say. Probably we need to put in a extra safety belt that does not delete "young" messages.

I agree. Lets see how quick we can incorporate it.

Not sure, but you might need a pattern and replacement like this: Pattern: (\*[0-9]*)@.* Replacement: sip:\*\1@\r;user=phone A lot of baskslashes! IT world meeting telephony world...

Check if you can make an outbound call to the number from that phone. If that does not work, then click 2 dial will also not work...

That will not work. Multiple domains require either an outbound proxy in the SIP phone or proper DNS entries.

No, when you are listening 1 is rewind backwards. You have to press "6" to move or copy it. Then you get into a special menu. Make sure you have the latest WAV files; there are some new prompts; if you don't have them you'll hear digital silence (there will be a LOG message about this).

Yes. See http://wiki.pbxnsip.com/index.php/Auto_Att...t#Night_Service. A dirty, but flexible trick!

I tried it here. For me it works - of course... However, I was using snom version 7.3.14 and there all SUBSCRIBE messages now show Expires: 0. Needed to change that to 3600, then it was much better.

What phone type? What firmware?

I would just use one auto attendant and 24 service flags. One falg for each hour. Then use the night mode feature to distribute the call to each cell phone: Service Flag Account: 7100 7101 7102 7103 ... Night Service Number: 9787462777 9787462778 9787462779 9787462780 ... You can even make exceptions for the weekend and for the holidays!

No, the blue line is the number of call legs. Usually one call equals two call legs. The red line is the number of calls, and in that graph the maximum was three calls.

You can try to set the ANI for the trunk and choose the mode "No Indication" for Remote Party/Privacy Indication.

Hmm. What if we just introduce a setting that says "maximum number of connected calls" in a agent group? In the above example, set it to "1" and then that poor guy who is on duty can work without phones ringing around him.

TFTP is UDP, telnet is TCP. Check out "netstat" from the command line to see what ports the PBX uses.

Do you get a admin email about the disconnect? That would be a clear sign that the PBX thinks the call dropped. Also, check if the AudioCodes has VAD turned on (turn it off if that should be on).

Full CO-lines are not triggering the failover... Only a full PSTN gateway can trigger that trough a SIP response (ideally, a 5xx code).

It sends an email? I would not know about that nor how to turn this off.

Which config file are you using to get the phone up and running? What firmware version?

Well, you need to know the IP address of the PBX server. Check out http://wiki.pbxnsip.com/index.php/Login for more information.
