I find that any sort of data (which includes fax) over VoIP on a BT
ADSL link is unreliable. OTOH, it works just fine if you're running
VoIP over an internal LAN, or over a high speed leased line.

(I've found practical uses for fax-over-VoIP on an intranet, so it's
not quite as silly as it first sounds.)

The problem is related to the jitter once connected, so it doesn't
actually matter whether it's incoming or outgoing.
