Running CUCM 8.6(2) integrated with a SIP service provider without a CUBE (customer doesn't have an ISR available)
All working ok, however does anybody know if there is a way to specify a wild card on the trunk for the list of IP addresses on inbound calls? The SIP service provider is establishing calls from multiple different host addresses within 2 x class Cs. At the moment, I'm adding multiple SIP trunks and allocating 16 IP addresses to each trunk and it is getting messy. Is there a better way?
