DID problem

Unanswered Question
Dec 4th, 2008

I have a pbx which connected to PSTN.

the pbx is connected to a router via ISDN E1.

when my users dial 9 they want to hear pstn dial tone.

right now my users can make call with pstn without hearing dial tone.

for solving this issue I have provided

this config:

dial-peer voice 5 pots

incoming called-number 9

port 0/0/1:15

after this config they can hear a dial tone after pressing 9

but the problem is I have other dial-peer too..

now they dial any number then they can hear dial tone!!!

when I provided DID on other dial-peer execpt above dial-peer

now the problem came back and they can not hear dial-tone again after pressing 9

please let mw know your issue or hints.

I have this problem too.

If you have been using CUCM i suppose that there is an option in the route pattern configuration page to provide outside dial-tone.

Please do check if this option helps you...

No Dial Tone On Digital Voice Port

Check to see if the dial-peer pots are configured with the direct-inward-dial command. This command disables dial tone from the voice port. For example:

dial-peer voice 1 pots

destination-pattern .T


port 0:DIf you remove the direct-inward-dial command from the dial-peer pots, then the digital voice port provides dial tone.

Also can you please upload the config for that especifically POTS.


if this helps, please rate

u can make dial peer as 9 only whihc open the line to the pbx then the pbx should handel the dialed number

or send the 9 to the pbx and configure the pbx to open the pstn line if 9 dialed then after user dial 9 will go to the pstn and then can dial normally
