[SIPForum-discussion] Making a call to a sip trunk

[Santosh Iyer]

Every provider has different requirements for authenticating and allowing calls on a sip trunk, so its best to discuss with the provider to understand what they are looking for. I will list few of the examples here
-> Might need a one time registration from the PBX-> Might need an hourly or daily registration from the PBX-> Might need to see a valid number that the trunk recognizes in the user from header. For eg the mainboard number may be recognized but an individual extension might not.-> Might want to see the trunk IP in the host part of the to header.

RegardsSantosh.

Hi all,  Is there anything extra required in order to test a sip trunk ? Any change to the SIP Invite message? From a user-agent’s point of view?  Thanks,Badri.
