cme secondary dial tone


I set up a customer with a cme 3.0 system utilizing fxo ports for outbound calls. Users dial a 9 to place a call so I added the secondary dial-tone 9 statement to the router. When users dial a number the display on the phone says To 9 immediately and doesn't display the rest of their dialed digits and also makes the called numbers directory useless.

I removed the secondary dialtone command and changed the dial-peer destination pattern to 9.T and that makes the calls display properly but that causes me to run into interdigit timeout issues.

Am I missing something or is this the expected behavior when using the secondary dial-tone command?

Re: cme secondary dial tone

That is the expected behavior with your dial-peer and interdigit timeout configuration. I would recommend using 9.T but setting the CME interdigit timer a bit higher, say 4-5 seconds. You can do that by:

dial-peer voice 1 pots

destination-pattern 9.T

port 1/0

dial-peer voice 2 pots

destination-pattern 9.T

port 1/1


timeouts interdigit 5

secondary-dialtone 9

Make sure you set it in CME and not on the ports themselves, they won't work. To recap with 9.T: the 9 matches your outside line, the . matches any digits up to T which is the interdigit timeout value (5 seconds). If the interdigit timeout is too long, you can always put a # after you dial to break the timeout .. but that is usually not acceptable for most users.

At home I use a configuration which lets me dial any NANP number without dialing a 9.. mine looks like this:

dial-peer voice 1 pots

destination-pattern T

port 1/0

forward-digits all

This works pretty good and I can still dial local extensions as well. Hope this helps some.
