CME - Dial peers to prevent call fraud from unauthorized sources

[rajesh.kumar]

Hi

CallManager Express 8.0 with E1 PRI and DID numbers.

Also there is CUE module exits in this router. Router IOS is 15.x

How do we configure Dial peers to prevent call fraud from unauthorized sources?

Hi clileikis

I have gone thorough the link, one you attached.

trust list under, voice service voip is for VOIP calls right.

there is one command : dial-peer no-match isdn disconnect-cause invalid-number

This command will disconect not matching dial-peer or default dial-peer. Do you have any solution for matched dial-peer (phone does not exists, but ephone configured), in that scenario CME should not provide outside dial-tone.

Pls. suggest if anything else need to be configured prevent call fraud.

Hi Rajesh,

Have I worked with you on a TAC Case?

you could use

dial-peer voice 1 pots

incoming called-number .T

direct-inward-dial

This should get rid of the secondary dial-tone.

HTH
