WebEx Calling with TDM Gateway

[aniket0422]

Hello Guys,

Can anyone help with the WebEx Calling with TDM Gateway configuration.

I have registered ISR 4321 Router with Control Hub. Its status is online.

This router is already integrated with Call Manager as MGCP gateway and having E1 PRI line for PSTN connectivity.

want to use same router for WebEx calling.

All documents available are for SIP PSTN and not for TDM PRI Line.

can any one suggest what all configuration changes required in this case.

@aniket0422 just to understand the scenario, let me ask: the E1 PRI is MGCP controlled and you would like to use the same E1 also for WxC users, is this correct? Or do you have a separate circuit for WxC on the same router?

You need to NOT use MGCP and instead use a SIP trunk or H323 gateway to CCM, preferably SIP.  This will involve making dial-peers, etc.  You can then make a secondary SIP trunk to Webex Calling with dial-peers too and route your calls appropriately.  You may have to use different tenants and E164 pattern-maps depending on where numbers are being routed.
