my sip trunk provider has given me a user name sip123456 when I configure that siip trunk as a gateway, I can make calls out no problem but I cannot receive any inbound calls! Now I did a lot of investigation and I found out that the user name has to be set as the telephone number for inbound calls to work, is there any other ways to overcome that issue in freeswitch, as my SIP trunk provider is unwilling to change the user name to the matching telephone number?
For information I am unable to provide a log as the call does not even reach freeswitch, my provider does not wish to provide a trace, also this issue happens in Asterisk, and Fusionpbx too! Now to make sure that my findings were correct, I used a different provider with another client, which uses telephone number as the user name, and my configuration works on both incoming and outgoing. I'm sure you would say to dump the other SIP provider but my client wants to find a solution hence I am posting this question...
My sincere apologies for being unable to provide further information such as trace logs etc, but has anyone faced the same issue, if yes what other work around have you used?
