I have a Registered from UCM with Metaswitch, I have issue as below:
say SIP trunk User name : Userxyz and Host name IP : X.X.X.X
(1)If on SIP trunk :
“From Domain” set the host IP: X.X.X.X
and " From User:" set :Userxyz a
All below works OK:
Form IVR ==>Press 1 ==>external number 4168881234
From extension Follow me to external number 4168881234
From extension Ring simultaneously to external number 4168881234.
and so on related to external number.
(2)If on SIP trunk :
“From Domain” set blank
and " From User:" set blank.
All above mentioned external number related function not working any more. I believe this is some kind calling party number issue which cause the issue.
In some setup, I need fully control the outbound caller ID signaled from UCM extension or trunk , So I can not set above mentioned “From Domain” and “From User” fields, because I f I set these fields, it can not signal /transmit the UCM controlled Calling number anymore, it only shows the calling party number set on Metaswitch side.
