Hello List,
i search for the right place in kamailio to manipulate the dispatcher
OPTIONS packets to add an Contact header.
For uac generated traffic i can use the event_route[tm:local-request] from
the tm module.
But how can i manipulate kamailio *self* generated OPTION pings from the
dispatcher?
OPTIONS request for MS Teams must contain the Contact header of such a
format:
Contact: <sip:SBC_FQDN:5061;transport=tls>
I follow this guide (for opensips) and try to adapt that step by step to
kamailio:
https://blog.opensips.org/2019/09/16/opensips-as-ms-teams-sbc/
CentOS 7 / kamailio 5.2.x (and maybe soon 5.3.x) / rtpengine

Hi Karsten,
Try this:
event_route[tm:local-request] {
if(is_method("OPTIONS")) {
append_hf("Contact: foobar\r\n");
}
}
U YYYYY:5060 -> XXXXXX:5060
OPTIONS sip:sip.XXXXX.microsoft.com SIP/2.0.
Via: SIP/2.0/UDP YYYYY;branch=z9hG4bK20ab.bd499990000000000000000000000000.0.
To: <sip:sip.XXXXX.microsoft.com>.
From: <sip:dispatcher@localhost>;tag=3393f0703fb0ccaca74109ff37de39f5-50a8.
CSeq: 10 OPTIONS.
Call-ID: 6b3a52797fe20b99-14352(a)127.0.0.1.
Max-Forwards: 70.
Content-Length: 0.
User-Agent: Kamailio.
Contact: foobar.

Hi List,
and of course here its an configuration problem on my side. I dont activate
the dispatcher probing in the module section.
Afterwards it pings. Now i have the fun to try and error further.
