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
