moh10ly Posted March 8, 2013 Report Share Posted March 8, 2013 I have a client who is testing Snom 710 phones, calls are disconnected whenever they try to call. what I can see in the logs are the alert "SIP: closing call -7 due to missing ack" I have advised my client to update their firmware since I saw this bug mentioned in the earlier firmware and has been fixed but my client is not even able to upgrade the firmware on the phone, it says (Software Update Downloading Firmware File not found error: 99) Anyone to help ? why is all this happening ? I'm attaching snapshots of the error on the phone firmware upgrade and the errors for calls. https://www.dropbox.com/s/qrnpjch0hqzf8ck/phone%20error.jpg 8/3/2013 10:01:39 [NOTICE] PHN: SDP: Skipped Codec G723 is not supported for 20 ms packets 8/3/2013 10:01:39 [NOTICE] PHN: SDP: Skipped Codec G723 is not supported for 20 ms packets 8/3/2013 10:01:41 [NOTICE] PHN: Resetting SRTP 8/3/2013 10:02:13 [NOTICE] PHN: SIP: final transport error: 1000053 -> udp:10.30.0.179:5060 8/3/2013 10:02:13 [ALERT ] PHN: SIP: closing call -7 due to missing ack 8/3/2013 10:02:15 [NOTICE] PHN: Fetching URL: snom://mb_exit 8/3/2013 10:06:53 [NOTICE] PHN: SDP: Skipped Codec G723 is not supported for 20 ms packets 8/3/2013 10:06:53 [NOTICE] PHN: SDP: Skipped Codec G723 is not supported for 20 ms packets 8/3/2013 10:06:54 [NOTICE] PHN: Resetting SRTP 8/3/2013 10:07:26 [NOTICE] PHN: SIP: final transport error: 1000057 -> udp:10.30.0.179:5060 8/3/2013 10:07:26 [ALERT ] PHN: SIP: closing call -8 due to missing ack 8/3/2013 10:07:28 [NOTICE] PHN: Fetching URL: snom://mb_exit 8/3/2013 10:09:00 [CRITIC] PHN: start_dst(1365303600) end_dst(1382846400) offset_dst(3600) offset_utc(7200) 8/3/2013 10:09:00 [CRITIC] PHN: start DST: 04/07/2013 03:00:00 (1365303600) 8/3/2013 10:09:00 [CRITIC] PHN: end DST: 10/27/2013 04:00:00 (1382846400) 8/3/2013 10:09:00 [CRITIC] PHN: SIP: Registered at registrar as 2440287@ (Expires: 1800 secs) 8/3/2013 10:09:00 [NOTICE] PHN: Settings stored! 8/3/2013 10:24:00 [CRITIC] PHN: SIP: Registered at registrar as 2440287@ (Expires: 1800 secs) 8/3/2013 10:24:00 [NOTICE] PHN: Settings stored!

Vodia PBX Posted March 8, 2013 Report Share Posted March 8, 2013 What version are your currently running on the PBX and on the phone? Assuming they are more or less up-to-date, this sounds like a routing issue. Are you using TLS? Then that problem should not exist at all.

moh10ly Posted March 9, 2013 Author Report Share Posted March 9, 2013 What version are your currently running on the PBX and on the phone? Assuming they are more or less up-to-date, this sounds like a routing issue. Are you using TLS? Then that problem should not exist at all. the calls between two telephone internally do not disconnect but only received calls from the ITSP provider disconnects. do you recommend using TLS ? if not what else would the problem be. the client have two dif vlan networks, one for VoIP and other for Data! I have provided my client the options to use in Vlan. Thanks btw, I'm not sure which firmware he's using but I think on the phone he's using 8.7.3.8.

Vodia PBX Posted March 10, 2013 Report Share Posted March 10, 2013 btw, I'm not sure which firmware he's using but I think on the phone he's using 8.7.3.8. I would definitively recommend to use 8.7.3.19 for the 710. Although it sounds like a rounding error, those two versions are quite different.
