Good morning, I am trying to register a new trunk in my system and a problem is occurring.
When I make an outgoing call, the trunk needs me to send the callerId(num) empty, leaving the FROM header in the following format “name” sip:domainname, however, when the trunk responds 200 Ok to the initial invite, it is modifying the header and placing in the following format "name"sip:@domainname. From what I managed to understand, that difference seems to be causing Asterisk not to recognize that 200 ok as a response… Am I correct? Thanks for the help.
I am using chan_psjip driver and the only difference between the FROM headers is that “@”.
