SIP Notify Answer event on T4 range - DMC_Support - 08-03-2017 04:34 PM
The SIP Notify Answer event does not work on Yealink T4 phones running Firmware v80 or v81. It does work on Firmware v71.
Steps to reproduce (on a phone running v81 firmware):
1) Register a T4 (e.g. T41P) to an Asterisk system. I used FreePBX 13.14.0 with chan_pjsip.
2) Configure the SIP Notify as follows:
/etc/asterisk/sip_notify_custom.conf
[yealink-answer]
Event=>answer=true
3) Restart Asterisk
4) Place a call to the endpoint
5) Send a SIP notify to Asterisk:
pjsip send notify yealink-answer endpoint 1011
6) The phone will not do anything although it does send a 200 OK response to the Asterisk system.
I downgraded the firmware to v80. I had the same problem.
I downgraded the firmware to v71. The SIP Notify Answer event worked as expected.
I have tested this on a T41 and a T46.
Has this function been deprecated or changed or is this a bug ?
Please let me know if you require any further information.
