Thanks for responding! However, that did not help. 

What I notice in the logs is that the tpn when I just use "proxy" instead of "Register-Proxy"  is tpn = tcp/xx.xx.xx.xx:5060 but when I use Register-Proxy it is with a *, like below.

/libs/sofia-sip/libsofia-sip-ua/nta/nta.c:2665 nta_tpn_by_url() nta: selecting scheme sip

/home/sharath/dev_branch/qsys/os/unpacked/freeswitch-1.6.19/libs/sofia-sip/libsofia-sip-ua/tport/tport.c:3257 tport_tsend() tport_tsend(0x7f4eec0074f0) tpn = */xx.xx.xx.xx:5060

Also, the messages like I said before contain the "transport=tcp" in both the Req-uri and contact header. Any other suggestions?

Thanks,

Shaks

FreeSWITCH 1.6.19 is very old, you need to upgrade.

I have the below gateways.xml file. FS 1.6.19.

<include>

    <gateway name="VoIP-1">

        <param name="outbound-proxy" value="xx.xx.xx.xx" />

        <param name="register-proxy" value="xx.xx.xx.xx" />

        <param name="proxy" value="xx.xx.xx.xx" />

        <param name="register-transport" value="tcp" />

        <param name="username" value="1222" />

        <param name="password" value="***" />

        <param name="extension-in-contact" value="true" />

        <param name="auth-username" value="***" />

        <param name="retry-seconds" value="30" />

        <param name="expire-seconds" value="3600" />

    </gateway>

</include>

But the REGISTER and the INVITE's are being sent out using UDP!. The strange part is the SIP headers both in the Request URI and the contact header contain "transport=tcp".

send 750 bytes to udp/[xx.xx.xx.xx]:5060 at 23:30:20.632901:

   ------------------------------------------------------------------------

   REGISTER sip:xx.xx.xx.xx;transport=tcp SIP/2.0

   Via: SIP/2.0/UDP xx.xx.xx.xx;rport;branch=z9hG4bKj7QXQX0X8tD3j

   Max-Forwards: 70

   From: <sip:1222@xx.xx.xx.xx>;tag=6Be8aaD192rcK

   To: <sip:1222@1xx.xx.xx.xx>

   Call-ID: a8905624-0576-421f-ba71-fb50c700e876

   CSeq: 9232391 REGISTER

   Contact: <sip:1222@xx.xx.xx.xx:5060;transport=tcp;gw=VoIP-1>

If I remove the Register-Proxy and Outbound-Proxy and just use Proxy everything works fine on TCP.

Also, if I set the transport param in the SIP profile to TCP things work fine. But I have multiple gateways in the same profile, so setting the SIP profile is less desirable. 

Am I missing something or is this a bug ? Any help really appreciated!

Thanks,

Shaks
