Calling between Cisco CUCM PBX and Webex

[Pavan Manjunath]

I need to establish a call between Cisco CUCM PBX and Webex. We have below infrastructure with us

on-premises 2 CUBE/ISR

ISR1: Cisco 2200 (Cisco CME is configured and running)

ISR2: Cisco 4400 (PSTN is configured and running)

Cisco Unified CM Administrator: v12.0.1 (licensed), v14.0 & v15.0(Evaluation mode)

Webex (Enterprise trail subscription)

With the above infrastructure, I need to configure Cisco to Webex setup. 

Need configuration details to achieve the scenario.

Thanks,

Pavan

@Pavan Manjunath everything is in the link that @dtibbe provided to you.  Open up the individual bookmarks, start from the top and work your way down.

Have you checked https://help.webex.com/jr1i3r/? There are many scenarios explained including Webex/UCM/LGW configurations

Thanks @dtibbe for your reply. Yes, I have checked https://help.webex.com/jr1i3r/? and trying to configure.

Currently, we have Cisco 4400 Series router and it has Cisco IOS XE Software, Version 16.09.02 with an existing PSTN gateway running. 

Now, we have to use the same Cisco 4400 router to create an another Local Gateway function for Webex Calling. Could you please guide me on how to proceed?

Let’s start by clarifying that having PSTN services setup in a Cisco router isn’t the same as a Webex Local Gateway. Webex Local Gateway is a way to integrate your on-premises CM with Webex Calling and can also be used for providing PSTN services to Webex Calling. Based on what you asked me in PM, you don’t need to be on 17.12, but 16.09.02 is very old and would likely need to be updated to something more current, like 17.09.04 for example. You can absolutely have PSTN services and Local Gateway services setup on the same router. It all comes down to your ability to handle dial peer configuration.

Thanks @Roger Kallberg The reply helped me to proceed further.
