I have just finnished to configure voipfone to work with my Draytek 2600V router. Voice is great, works like a charm...except....
When I dial into a phone conference, my meeting number (something like 123456#) is not recognised. The reply is something like 'the conference 112334566 is invalid'. BTW, tried US and UK conference system: same result....
DTMF is set to INFO SIP (tried Outband RFC 2833 but that was even worse)
and Codec is set to G711A (tried G711MU but same result)
