[Asterisk-Users] Zaptel lines locking up

[Rick]

We seem to be having problems at our office with lines locking up.

It mainly seems to occur when we have someone call into a Fixed Cellular
Trunk, at which point they use DISA to select an outgoing PSTN line or
the other way round, when a call comes in and is transferred out to the
cell phone. Although a few times it has happened to calls coming into
the office and being transferred out to a local number.

We are running *@Home 1.0 with 2 digium TDM04B cards, which has been
handling these calls fine for about 3 months and now all of a sudden
locks up. Originally we were just having the calls go to a extension
that dialed zap/g0, so when it started locking up we changed it to a
DISA command, but that made no difference. No other changes had been
made on the system for at least three weeks.

When zap barging the line we can hear screeching noises, similar to
modem noises then it just goes silent. We are using busydetect=yes and
busycount=6 and have not had any issues with line lock ups until a few
days ago. We did have another digium card issue where only port 1 would
respond, however we now run daily restarts and reprobe the cards.

In the CLI with show channels it displays the bridged calls with it
stuck on the DISA priority, as though its never detected the hangup.

Any help would be greatly appreciated.
