Inbound calls showing 9911

Answered Question
Jan 20th, 2010

Hi all,

We have an odd issue where several calls come in with the caller ID set as 9911. I am not sure why this is happening but the main problem is several internal users accidentally redial that number which calls the police and we get charged for a little visit by the men in blue.

I know it has to do with my dial peers for my inbound FXO ports but I can't seem to figure out how to fix it, here are my dial-peers:

Can anyone help me so that the caller ID doesn't show up as 9911?

Thanks,

Jorge

I have this problem too.

What might be happening here is that the inbound call is matching the FXO dial peer with destination pattern 9911, which is being put in the calling address field due to the fact that CLID is not being passed from the Telco. TO test this hypothesis, shut down all dial peers with destination pattern 9911 and make the call again.

The port configuration that you show is actually for the FXS ports, not the FXO.

Would you mind posting your whole config and just remove the passwords?

Also, this might not be a problem on the UC config, it could be the calls are actually coming with this as the caller ID information.

jorgediaz77 Wed, 01/20/2010 - 16:45

Yeah, we aren't quite sure if it is the config or that and a combination of an issue with our phone vendor that provides our rolling numbers. Anyway, I have attached the config. Thanks for taking a look!

Thanks,

This isn't part of the config.  The next thing we can do is get some debugs of an inbound call or call your PSTN provider.

Yeah, the telco is definetly part of the problem. We think it is because we have roll-over numbers on our block and some of the lines are dead so they get skipped. We are working with them currently to try to get Caller ID linked on all the lines as my boss thinks only some of the numbers in the block have the callerID tag on them.

Marcos,

How do I go about disabling the Dial-Peers through the CLI?

Thanks,

Jorge

jorgediaz77 Thu, 01/21/2010 - 07:45

That worked! Now my question is what impact does that have on my system to leave those dial-peers shut down?

Thanks,

Jorge

Marcos Hernandez Thu, 01/21/2010 - 07:51

That is not the fix. If you leave them shut down, they cannot be used for outbound calls. Try this:

1) Put the ALL_FXO trunkgroup under dial peers 50-53

2) Do a "no shutdown" of the peers you disabled

3) Test inbound calls repeatedly

We will need to enhance CCA in order to account for this use case. Let me know.

Thanks,


Marcos

Marcos Hernandez Thu, 01/21/2010 - 07:52

Or you could ask your Telco to enable CLID on those lines, which they will be happy to do for a nominal fee ;-)
