Hi all,
I have problem using DTMF on Snom Phones (300, 320 and 360)
I read they use in preference out-of-band DTMF , and if the remote system
does not support it they default back to inband.
I would like to use DTMF as out of band , and I defined
dtmfmode=rfc2833
in the peer configuration.
Nope, I am no able to access any ouside services using DTMF;
Another kind of phones, ATCOM AT320, can be configured as inbond or out of
band;
Again, If I use out of band (rfc2833) I am not able to use DTMF
If I use
dtmfmode=inband in the peer definition and in the phone configuration, it
works ( I am using g711 codec)
Anyway I wouldn't like to use inband, I would prefer to use gsm codec as I
know inband does not work very well with gsm codec
So the problem is: why my asterisk box defect on using rfc2833 ?
It is not a phone problem (4 phones of 2 different brands behave in the
same way)
What can I check in my asterisk configuration ?
thanks in advance,
Andrea
