Need configuration help on producing dial tone

[Virtusa Administrator]

Hello Experts,

I have a Cisco 2921 router with VWIC3-2MFT-T1/E1 card. On this card we have T1-CAS digital line connected. We have been provided with a set of DID numbers. We have a requirement where, when we dial a DID, the router should provide a dial tone, and should allow the user to dial to extension numbers. Not sure if this is feasible. If at all possible, will need to some configuration help.

Thanks

Sure it's possible. What's the T1 connected to? The router will offer two-stage dialing (aka dial tone) when the incoming POTS dial-peer does not have the 'direct-inward-dial' command on it. The router will accept any input and search for an outbound dial-peer (or ephone-dn for locally registered DNs) to match. Be careful if the T1 is connected to the PSTN as this is a toll fraud risk. You need to use CoR to reign in what outbound dial-peers are available to it.
