[Asterisk-Users] Transfering with Grandstream Phones

[MPlus]

I have the same problem with 2 ATA-286s, DTMFMODE=info and Dial command with
Tt options. Only the caller is able to transfer the call with the # key. The
callee is not able to transfer the call using # key, unless the codec is
ULAW and the DTMFMODE is inband. I suspect the problem is due the GS unit
because I failed to detect any DTMF INFO packets going into asterisk from
the callee using ethereal. DTMF INFO packets were detected from the caller,
though.
