[cisco-voip] direct-inward-dial

[Erick Bergquist]

FYI, You can also set the significant digits setting on the gateway configuration page to be 4 if you only want the 4 rightmost digits that are being being received. This way you don't need a translation pattern.  I have seen this save a few people problems in past when one day out of blue their provider was sending 10 digits instead of whatever their dialplan called for (4, 6, 7 digits, etc). 

Also, if site is in SRST and/or MGCP fallback mode, be sure to handle this on the router for when CCM is not available so the phones in fallback can get the calls if needed.

That is normal.

Realistically, you can request any number of digits to be sent by the provider, normally, they only send the last 4 or 5, however, they can send all 10 if you want.

With the Direct-inward-dial command, these digits will be passed to CCM (if MGCP), or to a voip dial-peer (of  H.323) and sent to CCM.

Ideally, you want to plan you numbering schema inside your network to match the number of digits that telco is sending you.

However, if it doesn't match, you can create a translation pattern on CCM to change it to the number of digits that matches your system... 

For example, suppose telco is sending you six digits that follow this pattern 4501 - 4933. You can create a translation pattern that matches 4XXXX and passes XXXX to the 4-digit extensions on your network.
