Hi,
I'm trying to figure out SIP trunks instead of PSTN lines and I've hit a little trouble.
I've got it configured so that out bound calling works from a user on my cucm to external numbers however inbound calling isnt working.
I have my cucm server, my cube router and the ITSP service off the internet.
My question is. how many dial peers should I have on the cube router?
I originally thought it was 4:
1 inbound from cucm to cube
2 outbound from cube to itsp
3 inbound from itsp to cube
4 outbound from cube to cucm
However now i'm wondering if it should only be 2...
1 in and outbound between cucm and cube
2 in and outbound from cube and itsp.
Which is correct? Or am I way off?
Many Thanks,
Tom

The best would be explicitly define the inbound and outbound dial-peer for inbound & outbound calls. as your call-flow topology has two broader sets CUBE to CUCM and CUBE to ITSP. so you need to create 4(two inbound and two outbound) dial-peer on the CUBE
CUCM----SIP----CUBE------SIP-----ITSP
- Inbound dial-peer for calls from CUCM towards to ITSP (to accept call legs from CUCM to CUBE).
- Another Inbound dial-peer to accept call legs from ITSP to CUB.
-
- outbound dial-peer for calls to SP from CUCM. (To originate call legs from CUBE to SP).
-Another Outbound dial-peer to originate call legs to CUCM from CUBE.
