Webex Calling!! Trunks, Route Groups and Dial Plans!


Cisco has enhanced Webex Calling to provide new local connectivity options for on-premises PSTN and PBXs, thus offering new scalable and redundant solutions to Partners and Customers.

Cisco Dial Plans, Trunks, and Route Groups provide Partners and Customers with the ability to manage calls between Webex Calling hosted users and premises PBXs users.

A Trunk is a connection between Webex Calling and the premises, which terminates on the premises with a Local Gateway (LGW). Once Admins create a Trunk, Admins can assign it to a Route Group.

A Local Gateway is an on-premises device(s) that interconnects the trunk, on-premises PSTN, and/or PBX.  LGWs enable hybrid migration journeys from on-prem PBX to the native cloud on a site-by-site or user-by-user basis.


A Route Group is a group of Trunks that allow Webex Calling to distribute calls over multiple Trunks or to provide redundancy. This adds scale and redundancy for Trunks to premises with priority, failover, and load balancing. This allows for better integration with premises PBXs and redundant routes to premises.


Dial Plans allow Admins to route calls to on-premises destinations by use of Trunks or Route Groups. They are configured globally for an enterprise and apply to all users, regardless of location. This allows for dialed digit translations and incorporates premises Dial Plans, which could direct Webex Calling to route outbound enterprise calls to premises PBXs or to accept inbound enterprise calls from premises PBXs.


The Route Verification Tool is a customer-accessible diagnostic tool is added to Control Hub, which enables an administrator to verify, or troubleshoot, dial plan configuration.


In conclusion, these multiple configuration enhancements are a continuation of the improvements that Cisco has in the roadmap for Webex Calling. These enhancements will bring a much improved and robust administrative portal for Admins and thus giving them very comprehensive configuration options.
