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.

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.

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:

CentOS 7 / kamailio 5.2.x (and maybe soon 5.3.x) / rtpengine
