[SIPForum-discussion] Blocking Specific Calling Number from PSTN

[Knupp, Varlei Fernandes]

Hi Zhou,

If the gateway is a AudioCodes or Mediatrix, Yes.

Because the AudiCodes Gateway can change destination number based in calling number.

Thanks

Subject: [SIPForum-discussion] Blocking Specific Calling Number from PSTN

Hello all,

As per the call flow below, could anybody guide me through how to block specific calling number from PSTN?
Is it possible that the incoming call could be blocked at voice gateway? If yes, how?

PSTN -> digital T1 ->SIP voice gateway -> Cisco Call Manager -> corporate user


Thanks in advance,

Howard Zhou
