[cisco-voip] wierd dialing issue 7 digit dialing

[Lelio Fulgenzi]

As far as I know, the only way to get 7 digit dialing working without delay is to eliminate any chance of the 7 digit number matching another 10 digit number. 

If you don't have 10 digit dialing in your area, then simply eliminate this option using route filters. The filter is based on "local area code" . 

If you do have 10 digit dialing, then explicitly define which area codes you service, this will minimize the chances of inter digit timeout, but will significantly minimize it. 

Hope that helps.

Subject: [cisco-voip] wierd dialing issue 7 digit dialing 

CM 7.1.5 
MGCP GW to 2921 ISDN PRI 

I recently converted from H323 to MGCP for my outbound call gateway. I know have an issue where 7 digit dialing is no longer working. I'm not using any route filters and my route pattern is setup as 9.@ 

The called party number type and plan is setup to Cisco CallManager and I'm using the NANP numbering plan. I tried changing the called party number type and plan to "Unknown". My Telco does allow 7 digit dialing and it worked right before switching to MGCP so I know that isn't the problem. My route patter is discarding PreDot digits. Any help would be appreciated. 

I can dial these formats: 

9-1-734-555-5555 
9-734-555-5555 

But not: 

9-555-5555 (it waits for the digits to expire then gives a fast busy) 




Here is what I get when I debug the call: 


Jan 9 14:07:58.301: ISDN Se0/0/1:23 Q931: TX -> SETUP pd = 8 callref = 0x123D
