2000IVS - Any additional ideas about what to look at regarding the following problem would be appreciated.
Problem: One Ground Start trunk in a trunk group works for inbound calls, but gives a trunk busy (fast busy) when accessed for outbound calls. Other trunks in the group work properly.
Troubleshooting thus far:
1. Checked the trunk at the Carrier demarc and confirmed that it is okay - able to pull ground start dial tone
2. Changed PN-4COTB trunk card - problem still remained.
3. Checked various trunk programming parameters, but didn't see anything out of order although obviously something is wrong.
4. No programming changes have been made to the trunk group in many years. However, the phone system did crash a few weeks ago during a power outage when the internal batteries ran out - I don't know if this problem existed before the crash.
