Inbound SIP trunk IP address wildcard

[barry]

Hi

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?

Thanks. Barry

Barry,

SRV records.

But why would they send calls from multiple desintations? Typically they provide single Proxy server IP address.

Thanks Chris

Working too late last night and should have thought of that one myself :-)

No idea why they are sending calls from multiple addresses. Outbound calls from CUCM only need to target a single IP address - however inbound calls are coming from all over the place....

Thanks again.
