I have a client with 30 extensions, all Polycom 501 phones, an Asterisk
1.2.30.2 installation, and trunking over SIP to TelIAX. Everything works
fine except where they need to use DTMF to navigate IVRs such as
Dell.com. The tones are not recognized at all.
My sip.conf lists for each extension:
dtmfmode=rfc2833
and in the [general] section: relaxdtmf=yes
I have a very similar system at my office nad DTMF works.
Any ideas why this does not work?
