RE: issue with anonymous calls on T22 and T28
The caller ID phone display derive from "PAI" or "From" header in SIP packet.
It's strange that only T26 in T2x series work if your server send a same packet to phone. Please check the "Caller ID Source" under Account-> Advanced, are they configured same?

If it still doesn't work, can you have a try of V73 firmware.
