[Freeswitch-users] Register-transport and Register-Proxy with TCP

[Sharath Kumar]

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 at xx.xx.xx.xx>;tag=6Be8aaD192rcK
   To: <sip:1222 at 1xx.xx.xx.xx>
   Call-ID: a8905624-0576-421f-ba71-fb50c700e876
   CSeq: 9232391 REGISTER
   Contact: <sip:1222 at 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
