SIP trunk with two ITSP's

Has anyone have sample config of single CUBE router, configured for two SIP trunks with different ITSP's?

I have logic in my mind, but wanted to include best.

Thanks in advance!

Hi,

while you hvae two SIP trunks from different providers then for sure you have two ranges of extensions.

You do not have any problem for incoming calls.

dial-peer voice 1 voip

desc incoming calls from 1st provider.

destination-pattern XXXXXXX

to CUCM

dial-peer voice 2 voip

desc incoming calls from 2nd provider.

destination-pattern XXXXXXX

to CUCM

For outgoing calls, you can use incoming voip dial-peer with translation rules to change the access code.

dial-peer voice 10 voip

answer-address XXXX

translation-profile (to replace the acces code , for example from 0 to 9 )

then outgoing voip dial-peers

dial-peer voice 100 voip

destination-pattern 9.T

to provider 1

dial-peer voice 110 voip

destination-pattern 0.T

to provider 2

Hi

We have New Features in Cisco Unified Border Element Enterprise Edition Version 8.5

Support for dial-peer bind: Dial-peer bind allows  Cisco Unified Border Element to connect to two different service  providers, where enterprise customers can connect to multiple service  providers for redundancy, call-type routing (internal, long distance,  and local to different providers), time-of-day (ToD) routing, or  least-cost routing. You can also use dial-peer bind on the Cisco Unified  Border Element inside interface if you need to distinguish source IP  addresses for different enterprise network segments or applications
