[Asterisk-Users] Cisco 7940 [SIP], DTMF and Voicemail

[Derek Conniffe]

Hi Doug,

Thanks very much - sorry I didn't see this in the wiki.  The details you 
quoted worked perfectly and I'm now on firmware V7.  I still have the no 
DTML tones recognised in voicemail but thats another problem.

All the best!

Derek
