No Dial-Tone through POTS dial-peer


I kindly ask for your help in order to solve an issue. I have the next dial-peer configured:

dial-peer voice 9 pots
preference 2
destination-pattern 9T
no direct-inward-dial
port 0/0/1:1 

From any IP Phone, when I press 9 in order to make a call to the PSTN, the dial-tone is lost, when I press the next number, the dial-tone comes back, what I want to do is that, when I press 9, the dial-tone does not lost. 

I have checked my route patterns and all of they have the "Provide Outside Dial Tone" enabled.

Please, if you need more details I will be happy to provide it.





Hi Ivan, its working as

Hi Ivan,


its working as designed. You have configured 9 to provide external dial-tone. So yes you would press 9 and hear nothing and dial the consequtive numbers provides dial-tone.


Rate the post accordinly.




Thanks, but do you know how

Thanks, but do you know how can I do this? Which parameter or command do I need to enter to mantain  dial-tone inmidiately after I press 9?




what you are after,is called

what you are after,is called "secondary dial tone" (also sometimes called two stage dialing in the more traditional PBX world, where a 9 was used to seize a trunk for external calls)

CUCM uses "provide outside dial tone" in the Route pattern definition. I am guessing you have some 9. pattern out there that has nopt got that box ticked and thus preventing a secondary dial tone to be played.  Please check that first.

Hi minkdennisI have reviewed

Hi minkdennis

I have reviewed all my 9. route patterns and all of them have the "provide outside dial tone" enabled. Another clue?



I'd check the route plan

I'd check the route plan report and search for anything that begins with 9.  You may have a translation pattern or directory number that begins with 9.  You can add the provide outside dial tone to translation patterns but not directory numbers so you'll need to delete any directory number that begins with 9.

Thank you very much Brian.I

Thank you very much Brian.

I will do this and I will inform you the results.



Thank you Brian.Effectively

Thank you Brian.

Effectively we have configured a directory number with 911, I have changed this  number and I have dial-tone again.

Best regards
