T48G Phones not disconnecting on Auto Answer for Intercom - telone - 05-14-2015 07:33 PM

2-T48G running software 35.73.0.50
We have a site running 6-12-65-27 vs 12.0.63
Have 2 stations with Yealink T48G phones both set to Internal Auto Answer=Intercom and not all the time but most of the time the connection remains open even if one of the station ends the call.
The most recent calls show 17 minutes and 22 minutes of activity in CDR when I look at the PCAP they both show that the RTP Stream ends 266 and 301 seconds sooner then the last SIP Packet.
We have other VPS running the same 6-12-65-27 software and Yealink phones with out this problem ?
As a FYI this site has a Sonicwall Router ( managed by the company IT company) we had many issues and have been able to resolve some but this seems to come back .
I changed the conference room setting to =app_meetme CDR show ConfBridge and *80xxx ( ext number)
The problem that is reported is always between the same 2 extension.
Any help on this would be greatly ap preciated
Thanks

Hi,
from your description , you meant the scenario is like below?
Two Yealink T48 locate in two locations,these two phone register the same account for example 100
Your virtual server make intercom to 100, both 100 will automatically answer the call.
the virtual server disconnect the call, normally these two phones should end the call and back to idle states, but actually these phones are still shows in the call .
right ?
How often the issue happen ? every call ?
have you checked whether the server send information to these two phones to end the call?
if there any brand phone can work well in this scenario ?

Best Regards!
Flora

Hi Flora
Thanks for reaching out
This is happening on extensions that are VPS and BLF is set to each extension- also in FreePBX (server -extension setting i set to Internal Auto Answer =Intercom)
When I look at the CDR its showing *80xxx =*80 is the feature code for Intercom prefix
I have tested other Yealink phones and the same setting does not set call as a *80xxx. They just dial the ext number (the CDR show it is just a dial not a *80xxx) and the auto answer on intercom and it open the path and if either party hangs up it releases the call.
These two stations that are the problem if ext 100 calls ext 101 with the DSS/BLF key when ext 101 leaves the call ext 100 stay connected ( just like if it was connected to conference bridge and when you press the speaker key or handes(pickup and hangup) it then terminates call.
That is the issue that I am trying to resolve-1 what is causing it to become a conference call and why if called extension hangup why is the caller party stays active 2-If I dial *80xxx manually it either party disconnects both ext disconnect

Thanks for your information.
so you mean ext 100 make a call to 101, 101 answer the call, 101 hangup the call but 100 will stay in the talking interface.
In this case, would you please check whether the 100 has received the Bye information ?
you can send me the trace that I can check .
Best Regards!
