"Callwithus"Setup CUCM

[KennethButler24475]

Hi guys,

I'm trying to implement the service from the vendor Callwithus to help reduce the cost of long distance calls, thing is though, even though I know a decent amount about navigating Call Manager,  I'm not familiar with how to get that going as I'm still learning Call Manager. What are a few first things I need to find out to steer me in the right direction? All help is appreciated. Below is just a photo reference to the vendors website in case that help at all.

I found the following on the configuration tab on their website under "Call Manager", I imagine this is what's required to get this going. I'm sure this isn't just a copy and paste job in the gateway, so what all do I need to modify here before adding the commands to the gateway?

dial-peer voice 77 voip
destination-pattern 77
session protocol sipv2
session target ipv4:sip.callwithus.com
dtmf-relay rtp-nte
codec g711ulaw
clid network-number username
!
sip-ua
authentication username username password password
nat symmetric check-media-src
registrar ipv4:sip.callwithus.com expires 120
sip-server ipv4:sip.callwithus.com

Also for the clid network-number & the authentication username & password, do I just create one in the gateway in place of the bold words or do I need to reference the usernames and password from elsewhere?
