RE: T27 V80 Firmware - BLFs Inoperable with Freeswitch
So all,
Interesting screwed-up situation. The Yealink does NOT send a REFER when attempting to transfer or place a call on hold during an inbound call. It works just fine with an outbound call. The inbound call, it sends an INVITE to the server. So what does this mean? That my server sends back a 481 Call leg/trans does not exist, and the call drops. I have officially exhausted all avenues, and am most likely going to return the phones. I've attached 2 pcaps. One of an inbound call, one of an outbound call. I'm hoping that you have seen this and can point me in the right direction. It does it every time so it's very reproducible.

In these pcaps, you notice I downgraded in hopes that .25 would work, but that wasn't the case. I'm happy to upgrade back and provide the same captures with the same behavior.
