Hi.
I'd like to use Kamailio as a SIP proxy routing calls to upstream SIP provider.
As far as I've understood the parameters I should set are:
pstn.gw_ip = "" desc "PSTN GW Address"
pstn.gw_port = "" desc "PSTN GW Port"
The problem is that my upstream provider uses dynamic IP for its server. How can I
use hostname instead of ip.
From what I see in route[PSTN] example it seems like it
should just work if I use
pstn.gw_ip = "sip.myprovider.lol" desc "My
upstream SIP host"
But if so - why the confusing name? And if not - how do I make it work? Is there
pstn.gw_host or smth like that?
regards,
Max.

Hey Max,
You should know that pstn.gw_ip is not a keyword in Kamailio and it
could've been pstn.lol_gw or anything. What really matters is that you know
where this gw_ip is being used in configuration.
Somewhere in the kamailio.cfg you'll see a PSTN route which will be doing
some RURI checks and then checking is pstn.gw_ip is not empty, and after
that it just modifies the RURI to contain this variable "pstn.gw_ip" value
in the Request Domain part so when t_relay() is called the call exits out
to that IP or Host.
You should search up on kamailio about DNS hostname auto-resolution and if
your provider has DNS SRV working how Kamailio will work with it.
Regards,
Sammy

yes, you can use it.

No pstn.gw_host, but if you prefer that, just change gw_ip to gw_host
everywhere in kamailio.cfg.
