History
Updated by Saúl Ibarra Corretgé over 2 years ago
WTF?! Just checked and it's really happening! Grrrr
Updated by Iñaki Baz Castillo over 2 years ago
Perhaps the registration is stored in DB (sqlite) and retrieved during application launch (this shouldn't happen of course).
Updated by Saúl Ibarra Corretgé over 2 years ago
Registration is not stored in DB. It's triggered when a properly instanciated account object is created. I'll have to check all initialization process.
Moreover, restart process (when configuration changes need to be applied) has to be checked so that nothing weird happens aupon reload.
Updated by Saúl Ibarra Corretgé over 2 years ago
I've not fixed it yet, but I found the issue!
Don't know why, but pjsua itself is discovering it's IP and updating registration! By looking at log:
23:30:41.438 pjsua_acc.c IP address change detected for account 0 (10.59.1.119:5090 --> 80.36.109.223:5090). Updating registration..
So what happens is:
- pjsua sends REGISTER with contact = PRIVATE_IP
- pjsua detects it's public IP
- pjsua sends UNREGISTER with contact = PRIVATE_IP
- pjsua sends REGISTER with contact = PLUBLIC_IP <------------ w000t!
We are not using STUN, so there must be an option to disable that... Hope to fix it right away!!
Updated by Iñaki Baz Castillo over 2 years ago
opsss, that's really strange!
However, a common wat to detect our public IP is by inspecting the Via "received" param in any reply from the server. For example, pjsip could take it from the first 100:
{{{
SIP/2.0 100 Trying
Via: SIP/2.0/UDP 192.168.1.100:8080;rport=8080;branch=z9hG4bKPjtjNiyMDjlmohCKId4gL-TChJr54JaOWI;received=YASS_PUBLIC_IP

CSeq: 16702 REGISTER
Server: Kamailio (1.6.0-dev0-notls (x86_64/linux))
Content-Length: 0
}}}
Anyhow, this must be a pjsip's configurable option and not enabled by default! Sure there is some way to dissable it.
Updated by Saúl Ibarra Corretgé over 2 years ago
- Status changed from Nueva to Resuelta
Fixed!
Look at this option and it's default value:
allow_contact_rewrite -- specify whether the account should learn its
Contact address from REGISTER response and
update the registration accordingly. Default is
True.
Now that option is set to disabled by default :)
In order to get the new option applied, delete your ~/.yass directory.

It would be a bood option in some "advanced" SIP menu configuration.
Updated by Saúl Ibarra Corretgé over 2 years ago
Why do you think it would be usefull? We already have STUN support. If you think it'd be appropiate you are free to open a new task for release 0.5.2, this is an easy one :)
Updated by Iñaki Baz Castillo over 2 years ago
STUN is not as good when are are behind a router with various public IP's and different routes for different destinations, so STUN request get a different mapped public IP than the SIP request.
Of course, taking the public IP from the "received" param is just useful for signalling but not for media.
However all this stuff will be improved when "draft-outbound" is a RFC since it states that a SIP proxy must implement a STUN server in the port 5060.
Yes, better forget my suggestion ;)
