Outbound Calls Fail Randomly

[simply-inc]

Need some help troubleshooting a strange outbound PSTN failure.
I have a fresh install of PiaF 1.2 with 2 TDM400P's, very basic/default configuration.
Inbound calls work great, extension to extension calls work great, but outbound calls "mis-dial" 75% of the time. I'm using the default "9|." outbound route and g0 trunk.
If I redial the same number over and over, it goes through once in a while...and the failures come back with a "dialed incorrectly" response from the carrier. I've tried local, long distance and 800 numbers all with the same result.
The asterisk -r session lists the same thing every time I redial, and it appears to dial correctly. The response from the carrier seems to confirm that I am getting out successfully, the carrier just appears to receive an incorrect dial code.
I've tried this same configuration with the TDM400P and a TDM800P...same results.
This new system is replacing an old asterisk system that did dial correctly, so I'm fairly sure this isn't directly related to the carrier.
Is there some type of protocol or signal tuning that can be done with PSTN trunks?
Any help would be greatly appreciated.
Thanks in advance!

Here's an example of the asterisk -r read out for a call that failed...

Try putting

relaxdtmf=yes

in zapata.conf

If that doesn't fix it, add a "w" to your dial rules in the g0 trunk. It will look like:

wNXXXXXX
wNXXNXXXXXX
w1NXXNXXXXXX

The "w" inserts a short pause that some PSTN providers seem to need. You can add several if you like.

Found the problem...we were dialing too quickly and loosing the first digit or two.

Prefacing "w" to the outbound number fixed it.

Thanks jmullinix!

Help on this....

Hey John,
Tried to add a wNXX to the dial pattern section of my outbound route and it would not accept it. I tried w|Nxx and still would not validate. puzzling...

 

[jmullinix]

I should have typed:

w+1NXXNXXXXXX

My bad.
