Dtmf tones are not passing through

Hi All,

I m using asterisk 1.2.24 on CentOS HP Proliant ML-150, i m facing problem with dtmf tones which are passing through. I dial a IVR after connecting i press the keys but ivr goes on no more key acceptance. Can any one tell how can i resolve the issue.

regards…

Hi

Sounds like you have the DTMF mode wrong. check with your trunk supplier and check the peer settings as well

Ian

my sip.conf settings are:

[test]
type=peer
host=X.X.X.X
username=test123
secret=2001
fromuser=test123
canreinvite=no
disallow=all
allow=g729
allow=ulaw
allow=g723
dtmfmode=rfc2833

and according to them these settings are OK.

Atif

give it a try?

With these settings m getting problem i change dtmf to inband, auto with no luck, can you help me out this issue…

Atif

Hi
What handset are you using ? and what codec is established when the call is up

Ian

m using Eyebeam, n when the call is established it shows g729.

Atif

Do you have G729 codecs ? try changing the sip.conf to

[test]
type=peer
host=X.X.X.X
username=test123
secret=2001
fromuser=test123
canreinvite=no
disallow=all
allow=ulaw
allow=alaw
dtmfmode=rfc2833

Also make sure the DTMF mode of the eyebeam peer match as well

but i will consume much bandwidth with 30 agents i have only 1MB E1 link. What you suggest?

Atif

Hi I Know it will, but this is for testing, are the softphones remote to the server ?

also what does the sip.conf entry for the sofphones looklike

Ian

[2002]
disallow=all
allow=g729
allow=ulaw
allow=alaw
host=dynamic
type=friend
username=2002
secret=test
dtmfmode=rfc2833
canreinvite=no
context=default

Here is my user settings for Eyebeam user in sip.conf
