[asterisk-users] Asterisk 13.1.0/PJSIP peer IP address issue
Thank you for your note, Scott. I set rewrite_contact=yes for both contacts, and I also had to do remove_existing=yes because I had to remove the existing contact information (max_contacts = 1 was preventing new contact information) using pjsip qualify demo-alice etc., after which the right IP addresses showed in pjsip show endpoints. Anyway, it works as expected now, I think. My pjsip.conf is now [transport-udp] type=transport protocol=udp bind=0.0.0.0 local_net=192.168.1.0/24 ;Templates for the necessary config sections [endpoint_internal](!) type=endpoint context=from-internal disallow=all allow=ulaw [auth_userpass](!) type=auth auth_type=userpass [aor_dynamic](!) type=aor max_contacts=1 remove_existing=yes ;Definitions for our phones, using the templates above [demo-alice](endpoint_internal) auth=demo-alice aors=demo-alice mailboxes=box_a rewrite_contact=yes [demo-alice](auth_userpass) password=demo-alice ; put a strong, unique password here instead username=demo-alice [demo-alice](aor_dynamic) [demo-bob](endpoint_internal) auth=demo-bob aors=demo-bob mailboxes=box_b rewrite_contact=yes [demo-bob](auth_userpass) password=demo-bob ; put a strong, unique password here instead username=demo-bob [demo-bob](aor_dynamic) Thank you for your help!

[asterisk-users] Asterisk 13.1.0/PJSIP peer IP address issue
Well, I thought it worked, but it actually doesn't--I am able to get the caller pick up the phone, but for some reason, I cannot hear anything on either side no matter who does the calling. Again, my two SIP phones are on the local 192.168.1.0/24 network (do not go over the Internet) and the Asterisk server is located in the same network (not accessed over the Internet). Any help is appreciated. Does the fact that Asterisk is running on a VirtualBox VM on the same machine as one of the SIP phones matter? I am able to access the ARI REST interface of the Asterisk server quite fine on the host machine. I suspect it has to do with RTP not being set up, but all the codec support is there. Here's a log for the SIP request from 192.168.1.50: <--- Received SIP request (1229 bytes) from UDP:192.168.1.50:64009 ---> INVITE sip:6002 at 192.168.1.139;transport=UDP SIP/2.0 Via: SIP/2.0/UDP 146.115.163.234:64009 ;branch=z9hG4bK-d8754z-5803642ad92cbd00-1---d8754z- Max-Forwards: 70 Contact: <sip:demo-alice at 146.115.163.234:64009;transport=UDP> To: <sip:6002 at 192.168.1.139;transport=UDP> From: <sip:demo-alice at 192.168.1.139;transport=UDP>;tag=b661670b Call-ID: YmZiODE4Yzc2NmJmNzY5NDhkM2Y2ZDNhM2U4NTZmZmE.

[asterisk-users] Asterisk 13.1.0/PJSIP peer IP address issue [Spam score:10%]
My suspicion would be that the line o=Z 0 0 IN IP4 146.115.163.234? is causing the problem. Your SIP client is reporting it's external IP address for the audio stream rather than it's internal one. I would look at the settings in your sip client to see if it has any automatic NAT stuff (like using a STUN server) and disable it.

[asterisk-users] Asterisk 13.1.0/PJSIP peer IP address issue
?To sort out RTP problems, I would recommend: 1) on all endpoints use codec of allow=!all,ulaw -- this is or should be supported by all endpoints and eliminates any issues of mismatch, translation, etc., and can be adjusted later once everything is working 2) add an Echo() application to your dialplan so you can call it and check ?RTP to and from Asterisk 3) start with direct_media=no to run all the RTP through Asterisk first 4) packet capture at/on the asterisk server, as well as at endpoints if need be, to identfy if and where RTP streams are being sent and received. The goal being to get two way audio calls up through Asterisk, and then change one thing at a time towards your desired configuration and retest.

[asterisk-users] Asterisk 13.1.0/PJSIP peer IP address issue
Solved! The issue was that RTP flows were being established to the wrong IP address. I figured out this issue--I had to disable STUN in both SIP phones for this to work correctly. Still, I wish a working configuration for Asterisk, and two SIP phones in the same 192.168.1.0/24 network would have helped me tremendously.
