Re: [SR-Users] Kamailio and NAT

Thank you for your answer. The problem I have is with internet router doing to PAT to SIP port. I am already advertising public IP but unfortunately I cant know the public port I am using. 2015-12-28 18:17 GMT+01:00 Alexandru Covalschi &lt;568691(a)gmail.com <mailto:568691@gmail.com>>: AFAIK bye is usually sent to the address stored in record_route. Try setting changing record_route() to record_route_preset("PUBLICIP:5060;nat=yes:) 2015-12-23 16:28 GMT+02:00 Nelson Migliaro &lt;eng.migliaro(a)gmail.com <mailto:eng.migliaro@gmail.com>>: Hello, I am running Kamailio behind NAT. Kanailio has a private IP and I am relaying NAT to internet router. I am using: - #!define WITH_NAT - listen=udp:PRIVATE-IP:5060 advertise PUBLIC-IP:5060 - Patched RTP proxy including the advertise option And everything goes fine. I can make calls and have two way audio. The problem begins when the callee ends the call. BYE is not received in Kamailio (caller) I included the public IP using "add_contact_alias" because "set_contact_alias" was not adding the public IP. I included this in in NATDETECT (pre loaded router) if(is_first_hop()) { xlog("L_NOTICE","Metodo: $rm \n"); xlog("L_NOTICE","is first hop\n"); #set_contact_alias(); if (!add_contact_alias("PUBLIC-IP", "$Rp", "udp")) { xlog("L_ERR", "Error in aliasing contact $ct\n"); send_reply("400", "Bad request"); exit; } } I think the problem is related to destination that BYE is sent by the vendor. From what I see IP and port is taken from advertised in contact (PUBLIC-IP and 5060). The problem is that internet router changes the source port. Contact: <sip:999999999@PRIVATE-IP:5060;alias=PUBLIC-IP~5060~1> --- Is it correcto to add_contact_alias("PUBLIC-IP", "$Rp", "udp") in order to received new transactions or should I follow a different procedure???
