Contacts status is unavailable although endpoint is registered on softphone

Asterisk Asterisk SIP
1

I have this issue where the contacts for endpoints show status as unavailable although the softphone shows it is registered and I can make calls. When I call this extension from another side, as all contacts are unavailable none of the softphones will ring.

type = aor
max_contacts = 1
;remove_existing = yes
;rewrite_contact=yes
qualify_frequency = 60
maximum_expiration = 3600
minimum_expiration = 60
default_expiration = 120

type = auth
username = 105
password = xxxxxx

pjsip show contacts will show

If you uncomment rewrite_contact does that change things? It’s likely the client doesn’t accept incoming connections and wants connection reuse, which rewrite_contact will do.

Enabling rewrite_contact helps to solve the problem for 105 which is using the local IP address of the Asterisk server and using UDP transport. 140 which is using NAT + Public IP + TLS is still behaving same.

One more issue that is seen is that in pjsip show contacts each contact appears twice

I was using grandstream wave app , using Zoiper instead solves the issue for 140 extensions as well. There is a slight difference in the contact URI, zoiper adds ;r to the ContactUri. 140/sip:140@82.178.22.45:42975;transport=TLS;r , still its have two exactly similar entries in pjsip show contacts

Can you point to some settings that might fix this behaviour in the same app?

I don’t know the apps, so I can’t comment on that.

As for the double entries in “pjsip show contacts” this is a known issue and there is already an issue filed on the issue tracker for it.

Did 140 re-register? Have you done a packet capture to examine the traffic (pjsip set logger on) and see the actual source address?
