Question

A CUBE has two outbound VoIP dial peers matching calls to the PSTN provider. Dial peer 100 is configured with 'preference 1' and points to the primary ITSP session target, while dial peer 200 has 'preference 0' pointing to a backup ITSP. Both dial peers use the identical 'destination-pattern 9T' and both session targets are reachable. When a user dials a PSTN number, which dial peer does CUBE select first, and why?

Accepted Answer

Dial peer 200, because a lower preference value (0) is more preferred than a higher value (1)

Answer

Dial peer 100, because a higher preference value (1) always wins for outbound routing

Answer

Dial peer 200, because dial peers with the highest numeric tag are evaluated last and become active

Answer

Either dial peer at random, because identical destination patterns cause CUBE to load-balance equally
