Hello!
I have the following architecture:
- Kamailio with RTPEngine (with public access on IP *YY.YY.42.207*)
- Asterisk (with no public access, internal IP *172.31.69.198*)
I am using a Voip SIP (with public access on IP *54.XXX.XXX.44*) configured
as a Trunk on Kamailio using UAC Module.
The issue I am facing is that the SIP messages replies I get from the VOIP
provider are being destined to Kamailio's public IP (YY.YY.42.207) instead
of Asterisk's IP (as sent on the message).
For example, this is the 200 message I sent to the VOIP provider (I clearly
state that the contact is Asterisk sip:172.31.69.198:5080):
2022/04/07 14:17:19.260864 172.31.32.7:5060 -> 54.XXX.XXX.44:5060

But the ACK I get from them is destined to Kamailio instead of Asterisk:

This causes Kamailio to not know where to forward the message to...
Asterisk never gets the reply.
This is happening to one of the SIP Trunks I am using, with the other,
everything is fine.
Is there anything I can do to work around it (other than contacting the
provider to fix on their end)?
Thanks!
ps: I have attached the full SIP messages trail to help.
Hello all,
I’ve been trying to figure out how htable reloads happen. Does it replaces
the existing one or creates a new one, populates it from the db and then
renames it? The latter would be (I think) ideal, even if it uses more
resources.
Thanks!
David

Hello Expert,
We faces problem in utilizing lcr command line in "kamctl lcr show_gws",
whereas kamailio version is 5.5.4 which are new kamailio release, "kamctl
lcr show_gws" shown result "command disabled".
in this case, LCR module is already been uploaded and the systemd has been
running well active kamailio.
Could you share, what probably wrong in my kamailio configuration?

Hello all ,
Do you know any way to get the hostname of my server at kamailio runtime ?
The simple idea behind this would be ton import a specific environment file base on hostname.

good evening everyone,
can you please help how to parse following XML body and get the "<gml:pos>31.204359 -44.512358</gml:pos>" in a variable?

xinfo("GML_LOC: $xml(x=>xpath:/pidf:presence/dm:device/gp:geopriv/gp:location-info/gs:Circle/gml:pos)\n");
and end up with error "unable to evaluate xpath expression":
