The external phone number mask is a method to present whatever caller id (CID) info you want to the outside world. As in, when I call you from my Cisco phone my number shows up as 555-5555, because my phone number mask is set to 555-5555.<\/p>\n

There are multiple places you can affect the number mask. As you move through the callmanager towards your destination, you have the ability to override the mask previously applied. The mask is generally applied on the extension.<\/p>\n

You can also apply it to a route pattern, translation pattern, route group or on the outgoing gateway. If you leave these guys set to “use calling party external mask”, then it will just pass through the calling info.<\/p>\n

If when you call an external number the CID doesn’t show what you want, the first thing to check is if you are sending the telco what you think you are. Issue the following debug command on the gateway:
\nterm mon
\ndebug isdn q931<\/pre>\n

This will debug your L3 call negotiation to the telco.<\/p>\n

In the picture above you will see that I am presenting the full 10 digits to the telco(calling party number)...I blocked out the last 3 digits...I don't want you fools drunk calling me ;) At this point, if you aren't handing the telco what you expect, look at the callmanager external masks. If it does match then you need to look at your \"calling numbering plan\" on the gateway.<\/p>\n

What we need to manipulate is the calling numbering plan. As you can see my telco needed my \"calling number plan\" set to ISDN. After you make the gateway change, be sure to reset your gateway, and you should be ready to rock.<\/p>\n","protected":false},"excerpt":{"rendered":"
