Sending OPTIONS/INFO keep-alives should be possible from the registrar. Sending just CRLF for keep-alive can only be done by the outboundproxy.
You could save() the REGISTER before forwarding to the REGISTRAR (or in a reply route if response=200 OK) and set the natping flag before. Then the oubtoundproxy should do the keepalive. regards klaus Am 13.05.2011 12:49, schrieb Asgaroth: > Hi All, > > I have a scenario where our registrar's are sitting behind our sip > proxy.
