Apparently this is a known problem past v8 firmware:

version-9/
I've done some more playing about and what I've noticed is that even when using
TCP SIP on the 8.x Firmware conferencing doesn’t work - making it use UDP
If I remember correctly, 9.x firmware dropped UDP support altogether.

Next step is packet capture to see if there is a clue as to the cause of
the failure in the SIP signalling.

Right, I see the following when running SIP Debug. Looks to me like the phones
are expecting the server to do the conference mixing, which I guess it would do
in CallManager?

Possibly slightly off topic, has anyone ever had Cisco 79xx Series phones come
up with cannot complete conference errors when trying to conference two calls
together?

I'm willing to bet you are forcing the use of G729. 7940 and 7960 phones can
only do a single G729 channel, and if you require G729 for the second leg of a
conference, it will fail.
