Too many changes at once...
Moved from old 720 to new 525.
Relocated data center at same time.
Dial phone lines at old site were managed by NEC pbx, 2 lines from a T1.
New Data center gave us 2 - AT&T lines.
Same Motorola 3260 modems, same comm config (but newer 2742 feature cards).
Problem is now approx 20-30 calls a day get a "no carrier" (out of perhaps 800-1000).
No code changes in 7 years.
Every dial starts with a vary on, call icf pgm, dial, comm, end pgm, vary off.
It has been suggested the NEC pbx must have managed the hangup better.
I know there must be a few dialers still out there.
Any suggestions.
