[Asterisk-Users] Cisco 7960 Transfer Call drop problem

[Justin Eckhouse]

Hi,
 
I'm having problems with transfer from an analog line via a X100p and Cisco
7960's running SIP.
 
With an attended transfer the a call comes in, I transfer it to another
7960, they answer I announce the call, press transfer again, the two parties
talk for 1-2 seconds then the analog line drops, though the Cisco phone is
not aware of this, i.e. nothing on the screen changes. The console output
for this is below. Interestingly enough I seem to have the same problem with
an incoming SIP call, transferring it to another SIP ext, console output
from that below as well.
 
With a blind transfer a call comes in, I transfer it to another extension,
the analog caller hears the hold music, the 7960 that was transferred the
call acts as if it is online with the call but isn't. If the extension that
was transferred the call puts the line on hold and picks it up then the
lines are connected fine.
