DiD/DoD in SIP Trunk

[yhab_dataconsult]

Dear All

We have a voice gateway  connected via 1 E1 (TDM) with the 20 channel DoD and 10 DiD. We will replace it with SIP triunk (IP based Network) and the customer require the same configuration (20DoD+10 DiD) Is it possible to do that with SIP Trunk.

Best Regards,

Yes, SIP supports DID. As far as DOD, I assume you want certain phones to call out with particular outbound caller ID. If so, yes this is possible. One way to do this is with voice translation rules to modify the caller ID based on the calling DN.

Hope this helps.
