Dear list members,

Even though I found extremely reasonable not sending any audio when a
PROGRESS message is received on a PRI channel (isn't it an early-media
session or one-way audio session?), nevertheless some Italian IVRs
expect the user to select the proper option by sending DTMF. Now my
asterisk box understands correctly the DTMFs on the caller SIP
channel, but it doesn't forward them on the Zap channel. Are there any
configuration or any other way to let the asterisk forwards the DTMFs
to a zap channel in progress?

Any suggestions are very appreciated,
Thanks for your attention,

Regards,
Francesco

PS I'm using Asterisk 1.4
