expressway core relay

[suthomas1]

Good day all,

Basic question here about conferencing setup. i have read up but not able to find reason for having expressway core along with expressway edge. what does expressway core do ?

edge is on the lines of NAT or TURN , so where does core chip in terms of functionality.

It doesn't mention it, but also webex edge audio and various of the Webex connectors also depend on the expressways.

Thank you.

What i am wanting to know is about expressway core functions.

If within an organisation Lan a user is joining a meeting room (eg.cms-meeting-room-1111.com) via laptop, does this request first go to expressway or does it go to cms server?

what is the best way to check on rms license available on expressway. we wanted to check how much are we using and if we need any more?

[zeuscyril]

you can check in the expressway option keys how many RMS license you have . try b2b calls to test the RMS license . you can use cisco b2b call tester.

hi 

Not necessarily going to expressway-c but Cisco Expressway has the capability of routing calls, among other things, based on the SIP variant detected. Specifically, it can distinguish between Microsoft SIP calls and standards-based SIP calls, such as those originating from Unified CM and Jabber.

you cab route calls using cucm also with sip route pattern.
