I have an issue where some random outbound 800 numbers ring busy. I have CUCU and PRI circuit. When I run debug isdn q931 I will get the following for the 800 that will give a busy signal, but another 800 number works just fine. The problem numbers work fine outside our phone system. My guess it is a routing problem with PRI carrier but not sure where else to look to prove one way or another.
Any feedback would be appreciated!!
Output that 800 not working – Cause i = 0x8091 - User busy
