[asterisk-users] Warm transfer issues in 1.2.10

[Dan Brummer]

Hello,
Well I was having transfer issues in 1.2.9.1 so I downgraded to 1.2.7.1.
For testing I installed 1.2.10 on a test server and setup two Polycom
SIP phones.  Tried the transfer on this configuration and had the same
issues.  Here is a log from the console:
 
This is how the flow goes:
 
Outside call from the PSTN to ext 1678.
1678 hits transfer button and dials 2175.
2175 answers call, speaks, then 1678 hits transfer again.
 
After that call just goes blank and we get nothing.  Is there a fix for
this in the latest build?
 
Thank you!
 
-Dan
