Hi Alex, As I said I was doubting about this inference, but as calls are working with other providers and I read the post I linked, I don't really know in what side the solution is.
The scenario is as follows: Softphone A - providerProxy - myProxy - Softphone B Softphone A sends the invite to Softphone B through providerProxy and myProxy Softphone B sends the 200OK with CONTACT: "user@softphone_B_contact_URI" to myProxy myProxy sends the 200OK with CONTACT: "user@softphone_B_contact_URI" to providerProxy providerProxy sends the 200OK with CONTACT: "user@myproxy_IP_address" to Softphone A Softphone A sends ACK "sip:user@myproxy_IP_address" and when it arrives to myproxy it is never sent to Softphone B and there is a timeout 30 seconds later. Is there anything I can do to solve this?

It seems odd to me... No, Ricardo, that is not the correct inference. First, if the ACK is an end-to-end ACK (as for a 200 OK), it is generated by the sending endpoint, and the SER proxy is not responsible for constructing it. Secondly, there are various reasons why an ACK may have a request line not equal to the Contact URI established as the dialog target, having to do with backward compatibility with RFC 2543. -- Alex Balashov - Principal Evariste Systems LLC 260 Peachtree Street NW Suite 2200 Atlanta, GA 30303 Tel: +1-678-954-0670 Fax: +1-404-961-1892 Web: http://www.evaristesys.com/ _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
