Cucm 12.5 more than 2 Pstn gateways

[Juraj Papic]

Hello,

I have a customer that actually has 1 PSTN E1 gateway, and now we are going to add two (2) PSTN gateways via SIP.

The two (2) new connections are for 2 different groups inside the company, I would like to know what will be the best practice be to make this work. All the company dials 9 to get out to the PSTN and for this 2 new connections they want to keep it the same way.

Thanks.

Hi Juraj,





On CUCM

Create Partition and CSS

Create Route Pattern 9 and assign above partition for new department users.

Create SIP trunk pointing to new voice gateway.



On voice gateway, create VOIP dial-peer accepting inbound calls from CUCM.

Create POTS dial-peer to send call to PSTN.



Regards,

There is absolutely nothing special about what you're trying to configure, same basic configuration you already have would be enough. I'd suggest you read the dial plan chapter from the SRND if you have doubts about call routing.

Best practice in my opinion, if these gateway are all in the same country, would be to put your separate groups of users into separate Device Pools.  Then use Local Route Groups for each Device Pool, and in the Route List.  Now you just need one set of PSTN Route Patterns, and calls will be directed to the appropriate gateway.
