I don’t think I’ve seen that requirement before, so someone else may have to answer if there is a PJSIP specific setting


However, if not then it may be simple to achieve the same result by using your firewall NAT rules.

Subject: [asterisk-users] SIP Source Port


Hi All.  We have a provider that requires us to SOURCE the SIP connection on TCP 5061.  I honestly have no clue how to force Asterisk to always SOURCE the SIP connection on a certain port.  


Can anybody point me in the right direction?  I am using PJSIP.


Thank you,
