Anyone have any hints on how to get the polycom ip501 to send dtmf
inband, our upstream providers require inband and the native rfc2833
format of the polycom does not work.
In order for inband to make it beyond Asterisk, you need to disable
rfc2833 control in the Polycom config file "sip.cfg" (i.e. via ftp
server).
tone.dtmf.rfc2833Control="0"
It appears that although Asterisk recognizes and uses inband dtmf
internally, rfc2833 is used on the external channel. I noticed this
behavior when remote IVR systems weren't acknowledging dtmf.
If that's your problem then just increase the DTMF length Asterisk sends.
/path/to/src/zaptel/digits.h
Change:
#define DEFAULT_DTMF_LENGTH 250 * 8
To:
#define DEFAULT_DTMF_LENGTH 450 * 8
Changing it to 350 is one of our standard patches to Zaptel that we use
internally.
This does not solve the problem when you do not control the Asterisk
server that connects to the PSTN, of course.
