Hi all,
we face a strange behavior while connecting an Asterisk16 instance
with PJSIP to 2 providers: we receive error 401 Unauthorized, both of
them having Kamailio as front-end. With other providers -we don't know
if they run kamailio- registration is just fine.
One of the provider took a pcap and told us that expiration was set to
0 that's why they don't accept the registration. We took a pcap on our
side when SIP packet goes out of our server and we see that the
expiration parameter is setted to 3600 !
Asterisk version is Asterisk 16.2.1~dfsg-1+deb10u1 on Debian 10 up to
date. We also installed 16.7 from scratch, same problem. I have to
mention that our test asterisk is also a Debian 10 with Asterisk stock
16.7 and _does_ register normally against the same provider :(
If someone had a clue on this, welcome.
We went a step further: when Asterisk is receiving the 401 Unauthorized
it doesn't send the Authorization back, insteed it send the Register
back with the *same* CSeq which it shoudn't. Pjsip is
pabx16*CLI> pjsip show version
PJPROJECT version currently running against: 2.8
