Summary:                    attended transfer weird behaviour
Description: 
Just installed 1.8.1-rc1 and tried the attended transfer function with 3
snoms (firmware 8.x), A,B and C. When A calls B and B transfers to C but C
is busy or does not answer, 'pbx-invalid.gsm' sound is played...but the
called number is right!

Another test: when I try to transfer the call to a wrong number I get this
message:
WARNING[31448]: features.c:1861 builtin_atxfer: Did not read data
and after that the call is bounced back to the transferrer (shouldn't
Asterisk say invalid extension???)

My test extensions:
exten => 12,1,Dial(SIP/81,5,tT)
exten => 12,2,NoOp(${DIALSTATUS})
exten => 12,3,Hangup

exten => 14,1,Dial(SIP/8,5,tT)
exten => 14,2,NoOp(${DIALSTATUS})
exten => 14,3,Hangup

exten => 17,1,Dial(SIP/70,5,tT)
exten => 17,2,NoOp(${DIALSTATUS})
exten => 17,3,Hangup

Please provide a SIP trace, console trace (with debug level logging) and a
trace with SIP history enabled in sip.conf.

Without that information it is going to be difficult (if not impossible)
to reproduce this without your hardware.
