bridge Inbound transport=udp to outbound transport=tls

[Jason Benedict]

Hello,
thank you for helping.
I have the following scenario (TLS is enabled in SIP profile both Internal & External):
========================
caller incoming (udp 5080) to Server A (udp 5080). Server A should bridge call to Server B (over tls 5081).
========================

I am just testing out but seem not able because I am getting in the Invite showing is UDP and not TLS.

Please share with me how in Dialplan -> Inbound routes, I should set up to achieve it? Doable?

Thanks.

If I'm understanding your question correctly, bridging outbound using TLS is fairly straight forward. You can pass all the required parameters in the bridge statement:

<action application="bridge" data="{rtp_secure_media=true}sofia/internal/$1@server.b.com:5061;transport=tls"/>

In the above example, we set a channel variable to enable encrypted RTP, {rtp_secure_media=true}, this is optional depending on your requirements. We are using the internal SIP profile in this example. $1 is holding the number you wish to call. Then we provide the destination server name and port. And finally add the parameter transport=tls
