Summary:                    DTMF problem on 1.4.17
Description: 
Hi,

when a call is being passed over from AS5400 via PRI to SIP into asterisk,
dtmf is working in 1.4.11 but not on 1.4.17

I ran some more tests with some interesting results.

The Aastra 57i works in SIP INFO mode if I change sip.conf and provision
the Aastra for SIP INFO

The Snom V7 320 fails the SIP INFO test.

This looks like a SNOM bug if SIP INFO is used.

The SNOM works well in rfc2833 mode.

However it does seem there is some DTMF suppression from extension to
extension.
Meaning the remote endpoint cannot hear any DTMF when it is issued by the
other endpoint.

I'll run a mess of tests tomorrow because something does not seem right.
