3CX Android Rejected call Auto Answers on T48

[James_Yealink]

Jason,

I received a reply from 3cx engineer Aram. I copy it here.

Quote:It is known issue (and can be reproduced on any phone) and there are the restrictions which user should know.
The problem is that he have somewhere 3CX Phone for Windows running in CTI mode and attached to the same extension. It is not allowed.
User can't use the following configurations:
1. Yealink Phone + 3CX phone for Win in CTI mode + 3CX phone for Android - he need to use the one of the 3CX applications, or the 3CX phone for Win should be in SIP mode;
2. "Ring my mobile simultaneously" and "Want to receive more then 1 call" are also not allowed to be used with 3CX phone for Windows in CTI mode;
3. "SIP_FORKED_ID" is also not allowed to be used with 3CX phone for Windows in CTI mode.

So, the customer have 2 choices to fix his problem:
1. Don't use 3CX phone for Win in CTI mode and 3CX phone for Android in the same time;
2. Open 3CX Management Console, go to the Settings->Advanced->Custom Parameters tab, find "SIP_FORKED_ID_BUSY" parameter and change value from 1 to 0.
In this case the PBX rejects incoming call "when one of the sip forked entities sends a busy signal, all invites to all participants are canceled at once".

Regards,
James
