I am having issues with Blind Transfer on asterisk 1.8
If I call from one Grandstream phone to another and us the transfer key
to do a blind transfer everything works fine.
When calling in on a sip trunk and then trying to use the transfer key
to transfer from Grandstream phone to Grandstream phone the call just hangs
up. It did not do this on Asterisk 1.4.x or 1.6.2.x . If we use the # to
initiate the transfer everything works. But our customers are use to using
the transfer key on the phone. I found several bugs out there on the bug
tracker but do not see if there is any work around. Any ideas or help
would be appreciated.
