    Transcoding

    Is there any way to buy additional g.729 licenses for version 4?

    Transcoding

    I think the problem is with CentOS. I have tried installing Snom ONE on my own CentOS VM guest and had the same problem. I suspect a timing issue, which is quite common in virtualization. Windows seems to manages it better then Linux. Transcoding is obviously very dependent on accurate timing, so it would make sense if this was the case.

    Transcoding

    You misunderstand. The transcoding doesn't work at all when using the appliance. If I load a Windows server guest with Snom ONE on the same host the transcoding works. The problem with the 10 concurrent calls is that I have had to force my extensions to use g.729 as well in order to avoid the transcoding issue. I am therefore now limited to 10 concurrent internal calls as well. I can live with 10 concurrent trunk calls, because we only have 10 channels, but only having 10 concurrent internal calls is a massive problem.

    Transcoding

    Thanks for the reply. 1. Our gateway provider only supports g.729, so we can't use any other codecs. 2. My problem with the transcoding is that it doesn't work at all. Irrespective of load on the PBX or VMware server. When I load Snom ONE on a Windows server guest on the same VMware host it works, so there is definitely a problem with the appliance. I have experienced this with multiple sites I manage, so I am confident that the appliance is the issue. Is there a fix for it? The problem with your 10 concurrent call limit and the inability to transcode means that all my calls (both internally and externally) are affected. If the transcoding can't be fixed I have to fork out for a Windows server license :-(

    Transcoding

    We are running the SNOM One VMware Appliance and are having problems with transcoding. Our gateway uses g.729, but with the SNOM one license model we are only able to run 10x concurrent calls. Our extensions therefore have to use other codecs. Internal calls are fine, but the moment we attempt calling through the gateway the calls are garbled and nobody can hear anything. Changing the extensions to g.729 solves the problem, but we are then limited to 10x concurrent calls both internally and externally. We are using SNOM One Blue 4.5.0.1075.
  6. Let's assume, for the moment, that it comes from the VM. Is there anything that I can adjust in CentOS to compensate for jitter being introduced when passing through it's routing layer? Thanks for the prompt response.
  7. Hi, Sorry about the late response. I ran the exact same config on Windows 2008 Server and everything worked well. Nothing has changed besides moving from Windows to the VMware appliance. Same host, same NIC, same network configuration. The reason for the higher latency is because the phone I pinged is on the other end of a 4km wireless link.
  8. Route are all fine: [root@localhost ~]# route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.133.0 * 255.255.255.0 U 0 0 0 eth0 169.254.0.0 * 255.255.0.0 U 0 0 0 eth0 default 192.168.133.254 0.0.0.0 UG 0 0 0 eth0 [root@localhost ~]# traceroute 192.168.132.220 traceroute to 192.168.132.220 (192.168.132.220), 30 hops max, 40 byte packets 1 192.168.133.254 (192.168.133.254) 0.387 ms 0.397 ms 0.433 ms 2 192.168.132.220 (192.168.132.220) 7.896 ms 7.887 ms 7.897 ms [root@localhost ~]# When an extension from 192.168.133.0/24 calls an extension in 192.168.132.0/24 (or vice versa) everything is fine. Snom ONE is in the 192.168.133.0/24 range. However, when a phone from the 192.168.132.0/24 range tries breaking out via the gateway (in the same IP range as Snom ONE) the quality suffers.
  9. Thanks, I'll increase the RAM now to see if that helps. I don't think it's swapping though. See below: top - 20:31:49 up 14 days, 2:46, 1 user, load average: 0.00, 0.00, 0.00 Tasks: 57 total, 2 running, 55 sleeping, 0 stopped, 0 zombie Cpu(s): 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 510596k total, 295108k used, 215488k free, 38380k buffers Swap: 128512k total, 0k used, 128512k free, 131252k cached I just left it at 512MB initially because that was the template's default and it worked fine under Server 2008. I'll revert tomorrow and confirm whether or not it made a difference. Thanks again for the assistance!
  10. Thanks for the suggestion. I used the defaults from the template (1 CPU & 512MB RAM), so no reservations or affinity. I have set affinity and a 1Ghz reservation now, but it made no difference. The other guests on the host are idling at the moment, so I'm quite confident that it's not a resource issue. Incidentally, the old 2008 Server had the same resource allocation. The quality issues make it sound like someone is talking through a voice modulator. Very strange...
  11. This is going to be a hard one to explain... We initially ran Snom ONE on Windows Server 2008 and recently migrated to the VMware appliance. All appeared to be going well, until we noticed complaints from certain users about call quality issues. Here's the scenario: Extensions on the same LAN (in the same IP subnet as the PBX) can call each other with no issues. They can also break out via the gateway trunk with no quality issues. Extensions in different LANs (different IP subnets) can call extensions in the same LAN as the PABX with no quality issues, but the moment they break out via the gateway the quality suffers and nobody can make out what anyone is saying. The configuration was backed-up and restored directly from the Windows instance to the appliance and the appliance is running on the same VMware host as the old Windows instance was. Any guidance would be greatly appreciated.

    PIN Codes

    Fantastic, thanks very much. The solution works and it already does ask for the extension number. Dialing the CC number first won't be a problem - most people are used to traditional systems where one has to dial a number for an outside line before making calls. I've forwarded the proposed solution to the IT manager for approval. Your prompt assistance is greatly appreciated!

    PIN Codes

    Thanks for your reply. I tried this before posting and the problem is that you can't use another extension's pin. Here's the scenario: ext 40 with pin 12345 ext 41 with pin 54321 The employee who has ext 40 assigned to them has to make a call from ext 41. When that employee uses his/her pin 12345 they get told that it's the wrong pin for that extension. The only way I've found to make it work is by hot desking, which is too cumbersome when one just needs to make a quick call.

    PIN Codes

    Is there any way to assign PIN codes to users (or people) instead of extensions? We have a retail store environment where casual staff come and go on a regular basis. In our current PABX store managers are given PIN codes, which have to be entered each time a call is made. I have been unable to find a similar feature in SNOM One. The best I could come up with was hot desking. The problem with this solution is that it is very laborious to always have to enable/disable hot desking before and after each call. Any other suggestions? This is the only stumbling block preventing us from rolling out SNOM One to our chain of 20 stores.
