T23G and T48G Fails to include transport=tcp in contact header - JMComstock - 08-27-2015 05:54 AM
Hello,
I'm having trouble with the new T23G phones. I'm using firmware version 44.80.0.60.
The same issue is happening on T48G phones when I upgrade to firmware 35.80.0.60.
I am also using NAPTR. The NAPTR resolves correctly to TCP with the correct ip and port.
When the phone registers it correctly uses a TCP port but fails to include the requisite:
"transport=tcp" in the contact header.
This cause the registration server heartburn because the connection is coming in on a TCP port but it is not specified in the header.
Here is an example from a T48G
REGISTER sip:p92dk.voiceelements.com SIP/2.0
Via: SIP/2.0/TCP 192.168.1.58:5060;rport;branch=z9hG4bK1589095695
From: "Reception" <sip:101@p92dk.voiceelements.com>;tag=264156176

...
Contact: <sip:101@192.168.1.58:5060>

When I return to firmware 35.73.0.50, it all works correctly.
REGISTER sip:p92dk.voiceelements.com SIP/2.0
Via: SIP/2.0/TCP 38.75.197.28:52501;rport;branch=z9hG4bK1884761878

Here is an example from a T23G with the incorrect header.
REGISTER sip:p92dk.voiceelements.com SIP/2.0

Problem is that I just bought a bunch of T23Gs because of discontinuing the T22P, so I am in a bind! There is no earlier firmware version to fall back on.
Please Help!!!

Hello,
Please upgrade phone to x.80.0.70 firmware. I test in a T48 with 35.80.0.70 and it works correctly.
Contact: <sip:6026@10.17.3.35:5060;transport=TCP>
Regards,
James

Hi. We just tried that on both phones:
On T48G
REGISTER sip:p92dk.voiceelements.com SIP/2.0
Via: SIP/2.0/TCP 38.75.197.28:5060;rport;branch=z9hG4bK4157743088
..

On T23G
REGISTER sip:p92dk.voiceelements.com SIP/2.0
Via: SIP/2.0/TCP 192.168.1.51:5060;rport;branch=z9hG4bK3745717080

Same issue. I think it is not working correctly due to the NAPTR.
When I change the Transport to "TCP" and put in the address that the NAPTR resolves to then it works (NOT USING NAPTR):
REGISTER sip:pbx11.voiceelements.com:5080 SIP/2.0
Via: SIP/2.0/TCP 192.168.1.74:5060;rport;branch=z9hG4bK700385971
...
Contact: <sip:125@192.168.1.74:5060;transport=TCP>
User-Agent: Yealink SIP-T23G 44.80.0.70

Putting back to NATPR breaks it again.
Thanks for the quick response!

Ok, Can you please send us a level 6 syslog? I will check with R&D.
Go to Setting-> Configuration, set the log level to 6 and reproduce the issue, then export it to us.
Thanks,
James

Downloading and testing now. Will follow up ASAP.
This fixed it. Thank you.
Can we get a firmware update with the same fix for the T48G?
