My problem with the procedure for
<hold> and respectively for <Transfer> in brief:
SNOM
D710 for testing
purpose using with Registrar – Telesis PX24Xr6 (Hibrid VoIP system).
When trying to use the
function
HOLD the call to be
hold, it is not hold but released. In the tracer we may see that after the confirmation<200
ОК> from the PABX, the
phone sends immediately <BYE> thus releasing
the connection. Apparently
in the <200
ОК> of the PBX is
missing a protocol element, needed to be received the confirmation from the phone
and to be continued the establishment of the next connection.
I have attached the trace from the phone itself - SNOM_D710_BAD_Hold_to_PX24X.txt.
The reason for the BYE is the result of us setting the Session-Expires: 3600;refresher=uas header making the TELESIS responsible for the session timer. TELESIS ACKs without the Session-Expires header and then sends a BYE.
Does TELESIS support Session Timers? If so can you try enabling it? Alternatively, you can try disabling timer_support on the phone.
Thank You for response. I have tried "disabling timer_support on the phone" and D710 no more adds Session-Expires: in SIP messages. But the problem is still present. Furthermore with the settings: Timer Support (RFC4028):on when D710 send <INVITE> with Session-Expires: 3600 and Telesis response with 180 Ringing and 200 OK both without Session-Expires: the call is established normally. So I attached trace from the phone itself without Session-Expires: -
I have send you via email latest firmware in order to test

Dear Pietro, No, the problem is still present. I have sent the downloaded .bin file to the customer, they made upgrade of the firmware, but the issue is the same. I'll try to go to the site so to be able to perform some more tests. In addition to mentioned issue the customer says that "in some calls there is one way missing of voice". I suspectthat thisis the main problemand the "BYE" is aconsequence of it. I willkeep you postedabout the problemas soon as possible. Best regards, A.Kovachev.

Hello.
I have read the topic https://helpdesk.snom.com/support/discussions/topics/6000042744, but i still can't solve the problem so my phone has no video, so where "disable video codec offer" in my model.
