Hello:

  I am using SER 0.8.14 stable. All is well except some users are reporting
that blind and supervised transfer, initiated from aCisco 7960 running 7.3
SIP image, doesn't work. Just dead air after transferring until eventually
the transfer timesout.

  ngrep and SER log output suggests the correct sequence of invites and
acks are being generated yet the calls do not go through. Has anyone else
experienced this type of problem? If so can you share some thoughts
on what is happening?

Thanks,Steve
