How to resolve long PDD
Post Dial Delay (PDD)
The time between punching in the last digit of a telephone number and receiving a ring or busy signal.
Resolution
Try to change Provider and see if it helps.
Open Asterisk CLI and watch how call goes. If you see:
Calling...
And then nothing to hear - that means Provider takes long time to deliver your call.
Linksys PAP2T ATA
In order for your PAP2T to connect the call immediately after you dial you need to set up a dial plan. On the web configuration page under the "Line x" tab at the bottom there is field for a dial plan. The dial plan tells the PAP2T which numbers to match, for example: (*xx|8xxxxxxx|0[2-9][2-9]xxxxxxx) matches feature codes, 8 digit number beginning with 8 and 10 digit numbers beginning with 0 and 2-9. More info on the Linksys dial plan format can be found in the IP Phone Admin Guide: http://www.linksys.com/servlet/Satellite?blobcol=urldata&blobhead... under 'dial plan examples'
