Call between two jabber clients outside the enterprise network

baktha.muralidharan — Mon, 18 Mar 2019 00:58:47 GMT

Hello

If a jabber client, located outside the enterprise network, calls another jabber client, also outside the enterprise network will the audio path still be through the expressway-E/C or will the audio flow directly between the two jabber clients, over the Internet. If direct, will the audio be secure, with SRST ?

Thanks in advance,

Audio will flow back to EXP C

Audio will flow back to EXP C/E for those calls.

What you mention, would require ICE, and that requires TURN. TURN needs to be disabled when using MRA, it's explained in the config guide.

I'm not sure why you mix SRST, or if that's a typo and you meant SRTP??

Jaime,

Jaime,

Thanks for your reply.

I was wondering if Cisco would implement the old-telco 2BCT type service with MRA.

Oops, meant SRTP, not SRST.

The concept is not applicable

The concept is not applicable, CUCM cannot be removed from the call as it has to keep control of the endpoints, as they're registered to it.

If you mean media routing, are you familiar with TURN/ICE?? If not, might want to google a bit to understand why I mentioned them before.

Yes, I meant only for media.

Yes, I meant only for media.

Thanks for the references! Bottom line seems to be that with MRA, media also has to flow through the expressways.
