[Asterisk-Users] PRI bi-directional early media

[Anthony Cennami]

I have a system configured as a VoIP/PRI gateway to a Shoretel PBX.  PSTN
connection is VoIP, PRI is connected to Shoretel.

It appears that the Shoretel will only provide inband DTMF, which is causing
problems for certain IVR applications which utilize early-media and
unsupervised DTMF.

Calls from a SIP phone are fine; calls via the PRI to the PSTN are fine as
long as the call completes and 200OK comes through.

Calls, specifically to 1800CALLDHL are heard on the PRI, but DTMF digits are
not detected.  My understanding is that via Asterisk, the PRI does not
bridge bidirectionally until the supervision/Answer has been processed.

Is there anybody out there that has seen/fixed a similar issue when using
Asterisk in a gateway application?

This is the only outstanding issue -- it is not any of the obvious
tx/rx/relaxdtmf/etc issues.  DTMF works completely fine (and is detected in
DTMF debug), EXCEPT when calling IVR systems that utilize early media.

Thanks for your help.

Anthony
