RE: Ringback not possible due to SIP server in 'telephone number'?
I have the same problem - however the problem started with firmware 35.80.0.60 on T48G - i didn't see the issue before.

I have also tested 35.80.0.70 - but same problem.

I have tried "user=phone" in From header. I have also tried changing the cis_source to 5 and sending the number as RPID header. Same problem.

The phone keeps dialing number@domain from the SIPS URI when dialing back from history on an incomming or missed call...

This is a big issue for us, as all new T48G comes with the new version firmware - and whats worse, they cannot be downgraded!

This has caused us to remove the T48G temporarily from our order form...

UPDATE! I just tried features.redial_via_local_sip_server.enable = 1 and it works - the problem is solved - thanks.

How ever, this should be default behavior, and not something that must be changed for dialback to work (at least it has never been necessary before...)
