blocking incoming collect calls

[janinegraves]

Hi,

This was asked by one of my students. Can anyone help answer it?

"I  would like to block incoming collect calls in the voice gateway,

but  I'm using R2 digital E1. I need to check the destinations numbers, and  depends of the number, It’ll accept or reject the collect calls.

On  the last PVT of Unified communications in Brazil, some people commented  of to do this block do with TCL scripts with Double-Answer, but I don’t  know much about TCL script."

Thanks, Janine

I'm not sure how you would block incoming collect calls in the gateway, unless all collect calls showed as from the same originating number.

However most telcos should be able to offer a collect call block feature.

Janine,

if i understand your requirement correctly..you can reject the call using translation rule and mapping to dial-peer.

Reject call on voice router

voice translation-rule 100

rule 1 reject /xxxxxxxxxx/

voice translation-profile reject

translate calling 100

voice-port x/x/x:23

translation-profile incoming reject

------------------------------------------------------------

First, create a translation rule that will identify the incoming call:

voice translation-rule 100

rule 1 reject /2124290000/

rule 2 reject /4089988472/

voice translation-profile call_block_profile

translate calling 100

dial-peer voice 111 pots

incoming called-number .

call-block translation-profile incoming call_block_profile

call-block disconnect-cause incoming invalid_number

Then place that translation profile into your inbound dial-peer. It you don't have one defined, create one using the incoming called-number dial-peer command, as so:

The call-block command allows the gateway to give a disconnect message rather than just a fast busy.
