Summary:                    unable to perform attended transfer of incoming call
from mISDN
Description: 
After talked with Blitzrage about bug 11085 on #asterisk-bugs we agreed on
opening a new bug.

Its always reproducible when there is an incoming call from mISDN. If
instead i generate the call from a SIP or IAX2 phone it does not happen.

The flow involves all GXP2000 phones with firmware 1.1.2.27, also tried
1.1.1.14.
The bug involes asterisk 1.4.13 also tried with svn-1.4.
mISDN used is 1.1.6 also tried to downgrade to 1.1.5.

The flow is like this:
1. SIP/12 answer call from mISDN on gxp's Line1
2. SIP/12 pick Line2 and call SIP/11 (mISDN get MOH)
3. SIP/11 answer SIP/12 and say its ok to talk with misdn people
4. SIP/12 pick line1 (SIP/12 get MOH) and say that the other people is
free 
5. SIP/12 hit TRANSFER button and press LINE2 and here happen the
problem:
- 90% of the time SIP/12 get a message onto the screen "TRANSFER
CANCELLED" and is unable to repick LINE2
- 10% of the time the call is transferred but is one-way-audio

I'll attacch full debug output.
