Hi Pierre,
Just a thought..check your dtmfmode in your SIP client configuration, if
your using inband but your codec is not ulaw or alaw the DTMF tones will be
misrepresented and thus will not be recognised due to the audio compression,
on the other hand if your phones are rfc2833 and asterisk
Hi Joanna,
Thanks for your reply.
In my mind I think it must be some setting in the client (phone) becasue the
Grandstream GXP 2000 does work and it is using the same sip.conf
Extensions:
6000 is xlite softfone
6003 is Linksys SPA941
6004 is Grandstream GXP 2000
6005 is Linksys PAP2NA
Please
Pierre,
Thats exactly what Joanna said in her reply.
Check the client DTMF settings on your phones.
set it to rfc2833 or out-of-band, whatever the config says.

Okay, in the SPA-941 admin I changed:
;DTMF Tx Method: Auto
DTMF Tx Method: Inband
and now it works.
Thanks!

Hi Pierre,
You can also add the following if you think its helpful.
relaxdtmf = yes ;relaxes the DTMF detection parameters
qualify = yes ; will send a SIP Optoin command regularly to check if the
device is still online, if the device did not answer within 2 seconds it
will be considered
