Hi Murf

I have tried the following methods before opening bug report:
-dedicated SIP transfer key (transfer fails)
-Aastra park key (transfer fails)
-Asterisk blind transfer (works)
-Asterisk one touch park (works)
-spre code (transfer fails and segfaults asterisk about 80% of the time)

Normally the spre behaves as SIP one touch transfer the spre attempts to
transfer to Asterisk park extension by completing the transfer on a single
line. Whereas the SIP transfer would normally invoke a second line.

spre code transfers used to work perfectly in Asterisk for me.

I also did some additional reading and some new settings in Aastra 1.4
firmware are required to complete a blind SIP transfer that does not
attempt to use a second line. This setting had no effect.

Aastra SIP transfers to park and spre transfers to park just don't seem to
work.

We'll patch to help with the segfault analysis. And I will wireshark
capture the SIP events leading to park failure.

Funny thing in manual is that park key is programmed and then some default
values are mentioned for certain SIP PBX's. Park is referred to as 700.
I don't see what is so special about this either...
