[Asterisk-Users] Unable to forward frame

[James Sturges]

Hi,

I get this error in the log file when I call from my mobile to the Asterisk
server, but hang up the mobile before anyone picks up.

Normally I would not worry about it, but I have been having some bad
experiences (only recently, after about 9 months of good operation) with
asterisk, although there have been related issues with Telco lines /
equipment and also some Asterisk initiated CRC errors after upgrading to
1.2.  So I have downgraded to 1.0.9.

So I can isolate everything I have just installed a VERY VERY simple dial
plan.

The setup is

Telco <---> TDM 4 Port BRI <---> Ericsspn BP250

Extensions.conf (all of it!!!!)
