[asterisk-users] problem with transfer application (REFER)

[Giorgio Incantalupo]

Hi nik600,

I had some trouble transferring calls with that version of Asterisk even 
if I used the normal transfer via features.conf. Upgrading to 1.4.24 
helped a bit (even if not completely). My advice is to upgrade to 1.4.24 
or the latest.
