I tried to set up the CUE functionality on the 520 series router. There is apropriate interface for the CUE:
ip unnumbered Loopback0
ip nat inside
service-module ip address 10.1.10.1 255.255.255.252
service-module ip default-gateway 10.1.10.2
there is static route:
ip route 10.1.10.1 255.255.255.255 Integrated-Service-Engine0/0
dial peer with the pilot number:
dial-peer voice 4000 voip
session protocol sipv2
session target ipv4:10.1.10.1
voice service voip
then I logged to CUE with:
service-module integrated-Service-Engine 0/0 session
There I have:
ccn trigger sip phonenumber 4000
username gpilat create
username gpilat phonenumber "201"
voicemail mailbox owner gpilat
and then forwarded on CME my 201 phone to 4000 (cue pilot number).
However I am getting busy signal. I tried to do some debugging but with no luck. SIP messages look OK between CME and CUE. Seems I am doing sth. wrong.
