Hi guys, First of all, I'm rather new to OpenSIPs and still struggling with details of configuration. OpenSIPs is used for "load balancing" in front of currently only one active and one standby FreeSWITCH servers.
As a starting point, I used the example config I found here: http://wiki.freeswitch.org/wiki/OpenSIPS_configuration_for_2_or_more_FreeSWITCH_installs#Edit_opensips.cfg Since it worked out of the box, I didn't change much: - enabled TLS support - modified addresses and ports listen=udp:222.222.222.222:5060 listen=tcp:222.222.222.222:5060 listen=tls:222.222.222.222:5061 disable_tls=no tls_method=SSLv23 fixed localcache.so -> cachedb_local.so with variables loaded sipmsgops.so Well, the problem is, that OpenSIPs doesn't consider the transport protocol, the sip client is using. Until now, all the clients were using UDP to register, so I didn't have any problems. But now, some clients need to register via TCP or even better TLS, because iPhone clients need a tcp session to be notified of incoming calls when the app is running backgrounded. Clients (iPhone Groundwire) can connect just fine via TCP or TLS, can make calls without any issues, BUT can't receive calls at all. (when registering via UDP, they can receive calls until they suspend the app) For starters, let's asume the client registers via TCP. Scenario: iPhone <TCP> OpenSIPs <UDP> FreeSWITCH Registering works fine with these protocols (the iPhone sends and receives TCP messages) FreeSWITCH's perspective: Registrations: ================================================================================================= Call-ID: E5D9A907EC8E61D20B0A59F00D5810FC20EF7D63 User: [email protected] Contact: "user" <sip:[email protected]:52364;rinstance=8AC2D8C4;transport=tcp;fs_path=%3Csip%3A222.222.222.222%3Br2%3Don%3Blr%3Breceived%3Dsip%3A17.17.17.235%3A52364%3E> Agent: Acrobits Softphone Business/2.4 Status: Registered(TCP)(unknown) EXP(2012-08-15 22:17:58) EXPSECS(91) Host: pbx.isp.net IP: 222.222.222.222 Port: 5060 Auth-User: 1002 Auth-Realm: sip.isp.net MWI-Account: [email protected] Total items returned: 1 ================================================================================================= So, there is ";transport=tcp" present and FreeSWITCH even says "Registered(TCP)" even though it never really sees any TCP packets from the client, or OpenSIPs.

So far so good... But then OpenSIPs decides to speak UDP with the iPhone, that has been registered via TCP and thus the firewalls won't allow the UDP messages to pass. -------------------------------------------------------------------------------------------------------------------------- Aug 15 22:16:48 pbxlb1 opensips[17018]: c1087393-61b8-1230-2c88-0016367615cd|start|received tcp request INVITE sip:[email protected]:52364;rinstance=8AC2D8C4;transport=tcp Aug 15 22:16:48 pbxlb1 opensips[17018]: c1087393-61b8-1230-2c88-0016367615cd|log|source 13.13.13.66:49684 Aug 15 22:16:48 pbxlb1 opensips[17018]: c1087393-61b8-1230-2c88-0016367615cd|log|from sip:[email protected] Aug 15 22:16:48 pbxlb1 opensips[17018]: c1087393-61b8-1230-2c88-0016367615cd|log|to sip:[email protected]:52364;rinstance=8AC2D8C4;transport=tcp Aug 15 22:16:48 pbxlb1 opensips[17018]: c1087393-61b8-1230-2c88-0016367615cd|log|originated from internal sources Aug 15 22:16:48 pbxlb1 opensips[17018]: c1087393-61b8-1230-2c88-0016367615cd|log|added this server to the route set Aug 15 22:16:48 pbxlb1 opensips[17018]: c1087393-61b8-1230-2c88-0016367615cd|pass|17.17.17.235:52364 Aug 15 22:16:53 pbxlb1 opensips[17018]: c1087393-61b8-1230-2c88-0016367615cd|start|received tcp request ACK sip:[email protected]:52364;rinstance=8AC2D8C4;transport=tcp Aug 15 22:16:53 pbxlb1 opensips[17018]: c1087393-61b8-1230-2c88-0016367615cd|log|source 13.13.13.66:49684 Aug 15 22:16:53 pbxlb1 opensips[17018]: c1087393-61b8-1230-2c88-0016367615cd|log|from sip:[email protected] Aug 15 22:16:53 pbxlb1 opensips[17018]: c1087393-61b8-1230-2c88-0016367615cd|log|to sip:[email protected]:52364;rinstance=8AC2D8C4;transport=tcp Aug 15 22:16:53 pbxlb1 opensips[17018]: c1087393-61b8-1230-2c88-0016367615cd|log|originated from internal sources Aug 15 22:16:53 pbxlb1 opensips[17018]: c1087393-61b8-1230-2c88-0016367615cd|log|forwarding based on the route set Aug 15 22:16:53 pbxlb1 opensips[17018]: c1087393-61b8-1230-2c88-0016367615cd|pass|17.17.17.235:52364 -------------------------------------------------------------------------------------------------------------------------- Strange enough: it still knows transport=tcp, so it _should_ be able to send it out via TCP, shouldn't it?

So I can't do any static packet manipulation, it should be as dynamic as possible. I'd really appreciate any hint in the right direction!
