Hello,
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:
N200: 3
N202: 3
K: 7
T200: 1000
T201: 1000
T202: 2000
T203: 10000
T303: 4000
T305: 30000
T308: 4000
T309: 6000 Our switch: Telcordia National ISDN 2: Range 10 - 90
seconds, default 90 seconds.
*
T312: 6000
T313: 4000
T316: -1 Our switch: Telcordia National ISDN 2: Range 10 -
120 seconds, default 30 seconds.
N316: 2
T-HOLD: 4000
T-RETRIEVE: 4000
T-RESPONSE: 4000
---end quote---
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?
Cheers,
j
