Getting Dial Tone on incoming calls

Answered Question

User Badges:

When a PSTN caller calls a DID in our office, the voice gateway sends a dial tone. Then the caller can press a valid 4-digit extension, then the call gets routed. I have 'incoming called number .' command in our VOIP dial-peer but the voice gateway still sends a dial tone. The configuration for the VOIP dial peer is as follows:


dial-peer voice 9000 voip

destination-pattern 3...

session target ipv4:10.20.30.40

incoming called-number .

dtmf-relay h245-signal h245-alphanumeric

no vad


Please advise, thanks.

The incoming called number should be matched on your incoming pots dial-peer not your VoIP dial-peer.


In order for DID to work, you have to configure direct-inward-dial on the pots dial-peer.


The incoming comming called number is then used to match an outgoing dial-peer such as your CallManager VoIP. This is achieved by configuring the incoming-called-number on the same pots dial-peer.


Can you try configuring your dial-peers as follows:-


dial-peer voice xy pots

description Inbound PSTN Dial-Peer

incoming called-number .

direct-inward-dial


dial-peer voice 9000 voip

destination-pattern 3...

session target ipv4:10.20.30.40

no incoming called-number .

dtmf-relay h245-signal h245-alphanumeric

no vad
