Chan_sip : to PJSIPSoftphones immediate go unreachable when on mobile if qualify is enabled

Asterisk Asterisk Endpoints
1

Hi , converting to pjsip, i used qualify before, but now with PJSIP, on local lan, all is fine
but on remote, with port 5060 open, and they connect, they go immediately offline after register
if i remove the qualify_frequence, then it works

seems asteriks isnt able to reach the port on phone side? why is that happening?
it worked perfect on chan_sip ?

[Mar 18 14:50:18]     -- Added contact 'sip:6000@100.70.xx.xx:39538;transport=udp' to AOR '6000' with expiration of 3600 seconds

Can anyone help me out? i’m still struggling with this…

i used before chan_sip, created a few extensions, opened port 5060 in router and the RTP ports
now with softphones i can register from public, but they are not reachable, i cant dial them, if i turn on qualify_frequancy, you see they go immediately offline after register

what is wrong?

thnx!!

You have no NAT options enabled on the endpoint, so Asterisk is trying to contact it at the IP address and port it has provided in the Contact. It said to contact it at 99.99.56.164 port 38883 - and that’s what Asterisk is doing. But it’s not reachable there.

If you want to enable NAT support in Asterisk for the endpoint, then you’d set the “rewrite_contact” option to “yes” and the “rtp_symmetric” option to “yes”.

ah, was indeed just reading about it

also this one? force_rport=yes ?

i have configured port forwarding on router from 9988 to 5060 , to make it less obvious :slight_smile:

The force_rport option is already set to yes by default.
