Thanks for the reply Mike,

I know that AQL have that issue but with this other provider both the
invite and the 183 progress have the same values and nothing looks out
of the ordinary. What's weird is that the provider claims that
something in FS is rewriting the DTMF length even though I've tried
manually changing it from 100ms to 300ms (to match the Cisco's
default).

Unfortunately Yehavi's suggestion isn't achievable either as the
provider doesn't support sip-info :(

Everything to do with RTP/DTMF is default and I've tried all the usual
tricks mention here: http://wiki.freeswitch.org/wiki/RTP_Issues.

Anyone else having these issues with Cisco kit?
