Hello,
I am experiencing a strange problem and I am wondering if anyone may have
some pointers as to how to overcome it.
I have an account with VoipTalk here in the UK which I have connected to
my Asterisk server. VoipTalk supports IAX2 and SIP and I have connected
to my Asterisk box using both methods. The problem is when I dial into my
Asterisk box via my VoipTalk incoming PSTN phone number from a landline or
mobile Asterisk does not consistently recognise DTMF's.
I have my VoipTalk context for incoming calls set to dial an extension in
my house then forward on no-answer to Asterisk voicemail. The idea is to:
--go into the voicemail box
--go to administrative options
--place an outgoing call
--dial a local extension that activates the DISA function
--Once in DISA, enter a DISA password and then it's possible to dial any
other locally defined extension.
When I hear my voicemail greeting I press star to get to the prompt where
I can enter my voicemail password. Asterisk seams to consistently
recognise both the star and my password. So far, so good!
Then, I press "4" for administrative options and "3" for
place an outgoing
call. Again this works fine.
The problem however is when I attempt to dial the extension assigned to my
DISA function. More often than not, Asterisk seams to miss my DTMF's. In
the event I do get to my DISA password prompt, it more often than not
misses DTMF's there as well.
I have this same problem no matter if I use IAX or SIP to connect to
VoipTalk. When connected via SIP I have the DTMF signalling set to
"inband" which seams to work as I am able to get into my voicemail box
as
I said above.
Can anyone offer a suggestion as to why it seams like Asterisk is
inconsistent with recognising DTMF's? Does it use different recognition
routines in different function s of the programme? Is there a way to
heighten the recognition sensitivity?
Any ideas would be very much appreciated!
Thanks in advance
Monty
