[Asterisk-Users] Transfering with Grandstream Phones

[Paul Tyreman]

Hi,

I have a problem with my Grandstream phone.  I have set it up to use
DTMFMODE=info and I am able to transfer calls that have been made from that
phone, but I am unable to transfer calls made TO that phone ??

I have tried every conbination of T and t in the extensions.conf file, but
all to no availe !

Can anyone help ?

Thanks, Paul.
