I seem to have an issue getting mid- registrar to work.



I have opensips with internal iP and fqdn say proxy.sip.domain.com



The asterisk/freepbx with pjsip extension at sip.domain.com



The two internal networks and dns resolution works fine.



The extensions can call each other directly through asterisk when linphone domain is sip.domain.com.

pjsip settings rewrite contact yes, direct media yes, from_domain sip.domain.com.



When linphone points to sip.domain.com with outbound proxy proxy.sip.domain.com I can call external numbers like cellphones and landlines but cannot reach internal extensions that
 need to go through opensips (ie mobile phones - for push notifications).



If from_domain is an ip calls reach (the uac debug shows the Bye received but no ringing occurs) but no ringing occurs so extension eventually goes to voice mail and can leave a
 voice mail.



One extension can call the other but not vice versa. The extension that can call the other two way audio is fine.



We have pn enabled = false for now until we can fix call issues period



calls do not seem to work at all without using the call dialog module but with the call module the issues above occur.



Here is what we find:



if we have opensips

socket=udp:10.x.x.x.x:5068 as proxy.sip.domain.com



pjsip info above with from_domain=sip.domain.com



internal extensions go to voicemail hear ringing from the calling extension but called extension does not ring.



Here is a copy of config with all removed ip and sensitive info - If a function is missing, it is not in the original as opensips does not complain on start.



Can you help me discern the issue. we used dialog only to get from uri for push notifications only when we enable push notifications (which we have disabled for now until we can
 get mid registrar to work)?



Other info to note: proxy.sip.domain.com, 172.31.11.60 and sip.domain.com is in the domain table. Tried posting config but list complains to big and moderator has yet to approve.
 Here is snippet:  Register works fine.
