keypad tone not recognised by conferencing system...

#1
Gurus,

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)

Any clues?

Thanks

I had the same problem on my Draytek 2800VG.

The fix (for me) was to got to VoIP >> Phone Settings >> Advanced Settings and set the parameter "DTMF Mode" to SIP INFO (cisco format) - it has worked perfectly ever since.

Thanks for the attempt.

But I already had DTMF Mode set to SIP INFO.

BTW, I can access the mailbox just fine, but the voicemail options are only 1 digit. In my case, it is like If I was pressing the key twice....

Anything else ?

Guys,

Ok, so I played a bit with the DTMF Settings , and here is where I am:

Code: Select all

+------------+--------------+---------------------+
| DTMF Mode  |   Voicemail  |   Conference call   |
+------------+--------------+---------------------+
|  SIP INFO  |    Works     | Failed (tone twice) |
+            +              +                     +
|   Inband   |    Failed    |     Works fine      |
+------------+--------------+---------------------+
Can anyone figure what I should do to get both voicemail and remote conf call working?

Thanks
