Ok, one step further. I need to use save() to add the phone as 'contact' when I get a REGISTER I get now keepalive packets to the phone, but ... I need them also to the PBX. I can not add the PBX as contact, because it does not register. I think there is no possibilty to add a manual entry in the usrloc memory. How can I also send the keepalive packets to the PBX?

Well, if you don't know the ip:port of the pbx and the pbx does not register ... but you should know something about the PBX, how do you send traffic to it and how do you trust the traffic from it?

Hi, The usrloc keepalive sends only via SIP OPTIONS.. Is this right? So it is not what I want Do I need some usrloc settings? Btw. I use kamailio 5.6

Thank you for your response! Yes, I found this already. But ... since I use kamailio as a transparent proxy I need to send also keepalives in the direction to the PBX. nathelper and usrloc only sends keepalive to 'saved' contacts from REGISTER messages. This works in the direction to the phone. But how can I also send keepalives to the PBX? The PBX never send REGISTER messages and I found no way to add an entry manually. Any idea for that problem? Unfortunately I use PJSIP at the phone and I can not send OPTIONS as keepalive.
