[Asterisk-Users] CAPI call transfer

[Jonathan]

Hi,

I am having trouble configuring CAPI so that call transfers work.
I make a SIP call to asterisk which goes out on ISDn via CAPI.  Then
I
try to do a transfer from the SIP phone which doesn't work and
results
in the call being disconnected.

The error message given by asterisk is that it chan_capi can't find
an
entry for the outgoing msn for the transfer however the outgoing msn
is the same as that used to make the original call.

Has anyone got any ideas please?

The asterisk trace and my capi.conf are below:

Thank you. Best regards.
