Hello!
I need to disable topos for one specific SIP trunk (in-out), it looks like
it’s enough to use event_route with IP address filtering.
But for some reason, the incoming INVITE from the peer still gets processed
by topos and I also don’t see a mention of [msg-incoming] in the logs, only
this:

Denis,
You probably need to specify the full address, including the mask, like:
1.1.1.1/32

Hi,
To disable topos for a specific SIP trunk, you can use event routes with IP address
filtering. It seems your configuration doesn't trigger event_route[topos:msg-incoming]
as expected. Ensure you have set event_mode to 5 to enable the necessary events and verify
that the IP address comparison is accurate. Here's a revised snippet:
modparam("topos", "event_mode", 5)
request_route {
...
}
event_route[topos:msg-outgoing] {
if ($sndto(ip) == "1.1.1.1") {
xlog("L_WARN", "[msg-outgoing] $rm/$rU/$sndto(ip)\n");
drop;
}
}
event_route[topos:msg-incoming] {
if ($si == "1.1.1.1") {
xlog("L_WARN", "[msg-incoming] $rm/$rU/$si\n");
drop;
}
}
Ensure the IP address 1.1.1.1 is correctly matched, and check if the event routes are
correctly configured.
Thanks

Hey!
I'm still trying to figure out how to implement an exception from topos
processing for a specific type of SIP device (IP is not fixed) based on
User-Agent.
If anyone has any ideas, I'd appreciate some help!

Hello,
there are two types of event_route that can be executed by topos, one
gives access to headers as well -- see the readme.
Cheers,
Daniel

Hey!
I'm still trying to figure out how to implement an
exception from
topos processing for a specific type of SIP device (IP is not fixed)
based on User-Agent.

I have been in the same situation. I have a registrar that handles UAs
and has a connection to our core routing instance. It also handles call
forwarding.
So when a call is directed to a registered UAs I want to engage topos,
but when the UAs times out or is unreachable and CFW is engaged
(sending the call back to the core to route to the CFW destination), I
wanted to revert engaged topos.
=> I found no way to do that. Further more, if the call is looped back
from the core to another customer on the same registrar, topos is
getting confused and breaks.
If you find a solution, I would be very happy to hear how you solved
reverting topos for a specific ip or for specific situations after it
was engaged.

Hey!
I'm testing the logic below, for now, it looks very promising.
It seems like there is access to dialog variables.
/*
SIP-UA (Snom) <--> Kamailio (w/o topos) <--> FreeSWITCH
SIP-UA (Yealink) <--> Kamailio (with topos) <--> FreeSWITCH
2 - execute event_route[topos:msg-sending]
8 - execute event_route[topos:msg-receiving]
*/
modparam("topos", "event_mode", 10)
request_route {
...
if ( is_method("INVITE") && !has_totag() && $ua =~
"snom" ) {
$dlg_var(no_topos) = "true";
}
...
}
event_route[topos:msg-receiving] {
if ( $dlg_var(no_topos) == "true" ) {
drop;
}
}
event_route[topos:msg-sending] {
if ( $dlg_var(no_topos) == "true" ) {
drop;
}
}

Hi Denys
I'm testing the logic below, for now, it looks
very promising.

/*

SIP-UA (Yealink) <--> Kamailio (with topos) <--> FreeSWITCH
Ok I think I know, why this does work for you, but not for me.
We have a very similar situation, where we use kamailio as registrar
like you do, but another kamailio (in router role) where you use
FreeSwitch.
The situation where we had calls signaling being completely messed up
by topos would be...
Call from Switch through Kamailio (with topos) to Yealink.
Yealink is busy!
Kamailio with topos activated at that moment, engages failure route.
Failure route determines YeaLink customer wants call forward on busy to
another number.
Kamailio routes call to Switch to take care to route to call to the CFW
destination.
Switch determines, that CFW destination is the number of the Snom UA.
Switch routes call to Kamailio (first call leg still present with topos
engaged).
Switch (in case it is Kamailio, it is a proxy, same CallID, same
FromTag from topos point of view)
=> Now things break. (don't ask me about the exact details how they
broke, it was just not behaving as expected).
I guess in your situation this works, as FreeSwitch probably works as a
B2BUA, therefore when the call is routed to kamailio a 2nd time, it has
a different CallID and FromTag and thus does not break the first
existing call-leg still known to the kamailio registrar.
