Hi
below are my configs:
pstn(e1)--->asterisk (span1)----->legacy pbx(connected via span2)----->
legacy analog extensions.
my dial plan is like callers dial into asterisk(span1) and they are connected to
the agents via the legacy pbx (which is in sync with asterisk on span2)....the
prob is when people call and when asterisk attempts to transfer the call, the
call dconnects with CHANUNVAIL error...
