if this has been posted before but I’m having an issue where I get the following

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt'>A
call comes in on our main to toll free number on an AT&T T1 line and is sent
to phone 4000. This is our secretary’s desk. If she leaves the desk she forwards
the phone to one of our sister companies so that they would answer the call. This
call is sent back out the AT&T T1. If she answers the call and then forwards
outside the building it works fine but if she forwards her phone outside the building
to auto forward the call when she is away from her desk we get the above error.
I have recreated this on my own phone (both hers and mine are Polycom 501’s)
and with a Cisco 7960. I also tried a different toll free number with the same
results. I searched the internet and found four people having the same issue
but none have gotten responses on how to fix it. Each time it was something
similar where the call was redirected. I know the T1’s are configured
correctly because all other incoming and outgoing calls work fine until this
error occurs. Then nothing works.</span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt'>I am
using Asterisk 1.2.7.1 with Zaptel 1.2.5 and Libpri 1.2.2. I have tried using
both a digium Wctxxp 4 port and RedFone’s Fonebridges and have gotten the
same result both ways so the problem is within Asterisk itself. I also tried
allow=all in sip.conf as well as specifically listing allow=slin and all other
formats to no avail. </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt'> </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt'>Also
when this happens the channel is no longer usable even though Asterisk thinks
it is available. When the next call is placed it times out because that channel
has been locked by the above error. The only way out is a complete reboot and
reset of all systems. Not good. </span></font></p>

help would be greatly appreciated. If I had hair left I’d be pulling it
out about now.</span></font></p>
