Asterisk Asterisk SIP

When i try to make call to header request will show “asterisk@ip address: port”
rather than contact number.
busy will be the status.

packet trace:–>

Contact URI: sip:asterisk@1x.xx.xx.xxx:5060
Contact URI User Part: asterisk
Contact URI Host Part: 1.xx.xx.xx

The user part of the Contact header, is completely opaque to any system except the one that generated it. The only purpose of the Contact header, in anything but registrations, is to provide a URI that will route back to the correct user agent.

There do seem to be a number of broken systems that read more into the Contact header than they are allowed to. I can’t remember if the previous threads came up with a workaround for this, but I’d suggest searching the forum to find those threads.

Although I haven’t used pjsip myself, the documentation appears to say that the contact_user is only used for registrations, and seems to be the equivalent of the callback address in chan_sip.
