I run CME on a 2651XM router with IOS c2600-adventerprisek9-mz.124-15.T9.bin. I know I can make multiple simultaneous outgoing calls on one sip trunk but what I wanted was several different phone numbers for incoming calls.
1) Can this platform do multiple sip trunks or do I have to upgrade to a later router? (which one).
2) would any of the latest IOS releases enable this router to do multiple sip trunks?
3) I read on this forum that I might be able to do multiple sip trunks if the provider didn't require me to register, but I've never seen a sip provider that operates without registration.
If I have to upgrade my router then ok but if there's any way to achieve multiple incoming phone numbers (DID's) on my 2651XM then I'd like to investigate that.
thanks for any advice.
