Sip trunk between callmangers 8.5 - 10.5. calls work fine. But when we call from 10.5 side the other end is not getting calling name. it is getting the calling number. when I do a Sip trace, I see that 10.5 is not sending calling name in the invite.
When a caller from 8.5 calls su, he does get remote caller I.d
I have checked the trunk config. I have changed all the calling presentations from default to allowed and also on the route pattern
but still no joy
