Calls with Caller ID "0" can't get connected

The user states that he can't talk and hear anything on incoming calls with caller ID "0". These calls get disconnected after 50-60 seconds automatically.

Does anyone know what's going on?

Re: Calls with Caller ID "0" can't get connected

How are the calls coming in? SIP/PRI/POTS? Is this a CCM or CME? What Version?

Are U translating on the way in etc?

We have PRI connections with AT&T and we are using CCM V4.2.

As for translation,I'll check it later.

Thanks.

Ok, what kind of gateway? MGCP? H323?

Re: Calls with Caller ID "0" can't get connected

if u r using H323 gateway we can block this call but if u use mgcp not possible to match it based on calling number !!

We are using H.323 Gateways.

Thanks.

Re: Calls with Caller ID "0" can't get connected

if u wanna block this call

do the following

voice translation-rule 1

rule 1 reject /^0$/

voice translation profile call_block

translate calling 1

now go to the dial-peer that point to ur PSTN T1 E1 ISDN what ever and apply it in the inbound direction

for example

dial-peer voice 9 pots

translation-profile incoming call_block

or apply it liek:

call-block translation-profile incoming call_block

this way any call comes to ur gateway with calling number "0" only will be blocked

good luck

please, if helpful rate

Re: Calls with Caller ID "0" can't get connected

I wonder if you could tell me why those calles can't get connected. The phone is able to ring but user cound't talk and hear.

Is something regarding to Gateway or CCM's settings?

Thanks.

Hi,

Thanks for this post. Can you explain what is the significance of /^0$/ here? I was not able to understand it from http://www.cisco.com/en/US/tech/tk652/tk90/technologies_configuration_example09186a00803f818a.shtml .
