Doubtful that T309 or T316 are causing the problem, but you can always change them to correspond with their defaults.

Subject: [asterisk-users] PRI timing settings
I wrote earlier today about a new PRI installation in the Caribbean, where all outbound calls are functioning fine *except* calls to Sprint phone numbers, which get rejected immediately as "busy".
The telco has been working with their switch manufacturer and took the output of "pri show span 1" from me and came back with this:
Please check your timers below. How did you determine your settings?
* Timer and counter settings:
T309: 6000 Our switch: Telcordia National ISDN 2: Range 10 - 90 seconds, default 90 seconds.
T316: -1 Our switch: Telcordia National ISDN 2: Range 10 - 120 seconds, default 30 seconds.
Now I have no idea what T309 or T316 represent, but it seems odd that timers and counters would cause such an odd result... and the failure is immediate, not after some amount of timeout. Can anyone shed light on these settings and tell me if they are configurable?
