Hi,
I've looked pretty wide on Google for this so I don't think it's been
asked before. Has anyone had experience integrating Asterisk with a 3COM
NBX system? The only way that I can see that looks possible is via the
3Com NBX ConneXtions H.323 product and then one of the H.323 Asterisk
I would guess that you have Echo squelch enabled in capi.conf. Either
disable this or use app_capiNoES (In the latest capi build) before
forwarding a call to voicemail. Beware, app_capiNoES does not check for
channel type so only use it on a CAPI channel.
Cheers
Martin
