About 18 months ago I was experimenting with a 4610sw running SIP off SipX. As I recall, codec negotiation on the Avaya phone was not working consistently. In the 46XXsettings file, I needed to restrict the phone to using a single codec G.711u in my case. I did get it to work.

So that's mean that Avaya phone 4620 with latest firmware doesn't support direct RTP communication, how can I prove it ? Best Regards. 2012/4/30 Cyril Constantin <[email protected]> Hi, Are you talking about the incorrect header checksum shown in the ACK ? (see in attachment) because I have this for Jitsi and Bria. Best Regards 2012/4/27 Tony Graziano <[email protected]> This may be a silly question, but what happens if you use a different hardphone other than the Avaya? The quick glances I gave at the pcap files said to me it was going to FS and it showed an invalid header from the UA.

The call is made from my softphones on my computer (3CX, Bria, Jitsi) and always arrive on Avaya phone and ring it but below it's whats happens: -- When it doesn't work: * I answer it from Avaya Phone and in my headset connected to my softphone I can hear the voicemail from sipxecs and RTP stream coming from Avaya mic in the mean time but no sound on Avaya speaker --When it works: * I answer it from Avaya Phone then I have both way audio. Best Regards 2012/4/27 Cyril Constantin <[email protected]> I have already only G711 Alaw / Ulaw but with video. I have deactivated the video and G711 ulaw, to keep only G711 alaw but it still the same. I'm facing the same issue with Bria latest release. Best Regards 2012/4/27 Tony Graziano <[email protected]> turn off all other codecs except g711 in jitsi and see if it is any different...

Regards 2012/4/27 Tony Graziano <[email protected]> Have you enetered anything in jitsi to enable stun or ice? do you have anything that defines rtp port range in jitsi?

I have tried to register my softphone and Avaya phone to Asterisk so see if the issue was related to Avaya phone but it works like a charm (maybe due to the fact that Asterisk do B2BUA) I couldn't explain why it doesn't work all the time but I suspect the fact that I had redundant server that I deleted some weeks ago maybe there is some residue of the previous configuration, there is currently only one primary server configured without HA. IP address of the computer where softphone are installed: 10.147.116.102 IP Address of the Avaya phone: 10.147.116.202 IP Address of Sipxecs: 10.147.113.221 I have attached traces from a call from softphone to 4621 working and not working, there is tcpdump from my computer, from sipxecs, merged.xml, sipXproxy.log in debug. There is also a screenshot from Wireshark where I have opened the both capture made from my computer, we can see the difference between both but I couldn't explain why. I don't think that it comes from my DNS like it's managed by Sipxecs automatically, I have attached the zone as well. Any help will be greatly appreciated. Best Regards.
