Also, if you are coming through a gateway make sure the gateway is equipped
to handle dtmf. On cisco you dial peer should look something like this:
dial-peer voice 10 voip
application session
destination-pattern .T
progress_ind setup enable 3
rtp payload-type nte 98
voice-class codec 1
session protocol sipv2
session target sip-server
dtmf-relay rtp-nte
ip qos dscp cs5 media

this is an asterisk problem not a ser one, if you debug the sip channel
in asterisk CLI, and then press the keys are the dtmf signals being
sent/picked up

Hi guys,
I currently have a sip proxy server (sip express router) which
registers the sip phones. I need to add voice mail capability, i.e.
sip express router will forward all incoming calls to Asterisk if the
user does not pick up the call in 15 seconds.
The voicemail recording stops when the user hangs up. However, the
recording does not end if the user presses the # key, i.e. it is
ignoring the user input.
Similarly, when the user dials 2102 to access his voice mail, Asterisk
plays the prompt, but it seems to ignore all the user input keys.
Please kindly advise.
Regards,
YY
