Thanks for the tips.

I have changed the NAT settings on the SPA2000 back to no NAT. I couldn't
find the via settings you referred to so I upgraded the firmware (from
2.0.10e to 2.0.13g) and there they were. Hmmm. Was I just blind or were they
really not there before???

X-Lite is not configured to use stun. I've still got no audio either way
with the settings below. The problem exists with and without stun settings:

Admin > advanced > Line 1
NAT Settings
NAT mapping enable: no
NAT keep alive enable: no

Admin > advanced > SIP
NAT Support Parameters
Handle VIA received:  yes
Handle VIA rport:   yes
Insert VIA received:  yes
Insert VIA rport:   yes
Substitute VIA Addr:  yes
Send Resp To Src Port: no
STUN Enable:  no
STUN Test Enable: no
STUN Server:
EXT IP:
EXT RTP Port Min:
NAT Keep Alive Intvl:  20

Any further pointers would be greatly appreciated.

Regards

Cameron
