PSTN connectivity

How is PSTN connectivity provided with Webex Calling?

Webex Calling allows you to locally connect your existing PSTN service to the Webex cloud using Cisco approved gateways.

What hardware, gateway, is supported to connect Cisco Webex calls to the PSTN?

Webex Calling allows your customer to connect their existing PSTN service to the Webex cloud using Cisco gateways. The following Cisco Unified Border Element (CUBE) devices support Webex Calling to connect to your customer’s PSTN service:

● Cisco 4321, 4331, 4351, 4431, and 4451 Integrated Services Routers (ISRs) using Cisco IOS® XE Software Release 16.9 (3)

● Cisco Cloud Services Router 1000 Series (CSR 1000V) with Virtual CUBE and Cisco IOS XE Software Release 16.9 (3)

● Cisco 1100 ISR with Cisco IOS XE Software Release 16.11

Note: CUBE Calling licenses are included in the Cisco Webex Calling Flex Plan license. CUBE selection requirements are governed by encryption and decryption needs. (Signaling and media to Cisco Webex Calling are always secure.)

 

An example of a gateway and software that should be used:

For Webex calls with fewer than 200 users, you can use the Cisco 4321 Integrated Services Router (ISR) with the required Cisco IOS® XE software.

The 4321 ISR will support up to 40 sessions, thus 200 users in a 1: 5 ratio. If you need more sessions, a more powerful router will be required. Here is an example bill of materials (BOM) for a 4321 ISR:

4321 ISR hardware ISR4321 / K9

+

Unified communication license for Cisco 4320 ISR SL-4320-UC-K9

+

Security license for cisco 4320 ISR SL-4320-SEC-K9

 

For environments with more than 200 users, we recommend an ISR 4331 and the required CUBE software. The 4331 ISR will manage up to 200 sessions. With a 5: 1 ratio, it can provide support for up to 1000 users. This will vary by customer.

Are the calls encrypted?

Yes, call traffic is encrypted end-to-end.

Can a gateway that supports the Webex Calling on-premises and cloud solution be used to support users?

Yes. One of the benefits of using a gateway to provide PSTN connectivity to cloud users is that it is an important first step in helping the customer transition to the cloud at the pace that best suits their business strategy.
