Help with Sipgate / Draytek 2600V / Sipura SPA 2000

I need some help with a setup using Sipgate, a Draytek
2600V and a Sipura SPA 2000 please.

Apart from Sipgate being a bum choice, I'm struggling with
one-way audio with the above set up. I have three Sipgate
numbers, one has a fax machine on it and is the only FXS
port used on the Draytek 2600v. This works OK using SIP
port 5062 (when Sipgate is working !) and the 2nd Draytek
FXS port is disabled in the set up.

The SPA 2000 is plugged into one of the LAN ports of the
Draytek. I want to use it for two voice lines using a BT
Converse 2025. I can call both voice numbers from the fax
line but I only get incoming audio on either line. I cannot
make any outgoing calls on either of the FXS ports on the
SPA 2000. These are set for SIP ports 5060 and 5061
and I'm using static IP addresses.

I know it's got to be something to do with the Draytek not
allowing certain ports through but which ones ???

Mike.
