T46G Firmware 28.80.0.60 disables the intercom auto-answer function

[Karl_Yealink]

Hi,

I had tested here, and T42G and T46G with your version all can work normally.
From the PCAP, I find the invite message don't contain the "intercom=ture". I think you don't capture the intercom process.

Please check do you enable the Accept Intercom(web interface->featuers->intercom) firstly.
Then check whether the server support the function.

If possible, please get the PCAP file again, note that press the start button then repeat the issue, and export the PCAP file.
