[Asterisk-Users] Asterisk crash: "using deprecated BYE/Also transfer method"

[Pavel Siderov]

Hi,

I'm experiencing some problems with my Asterisk 1.0.9. When a customer 
tries to use transfer method sometimes Asterisk crashes. The following 
message appears in /var/log/asterisk/messages

Nov 17 15:56:35 WARNING[759]: No path to translate from 
SIP/12.34.56.78-3aef(1) to SIP/domain.com-b6ccf248(256)
Nov 17 15:56:38 NOTICE[759]: Client '12.34.56.78' using deprecated 
BYE/Also transfer method.  Ask vendor to support REFER instead
Nov 17 15:56:38 WARNING[759]: Invalid transfer information from 
'12.34.56.78'

But it doesn't crash every time when customer tries to use transfer.
Any ideas ?

Thanks in advance,
Pavel Siderov
