[asterisk-users] A linksys SPA921 behind NAT and firewall

[Huw Richards]

On my SPA3102 on the Admin Advanced SIP page:

Subsitute VIA Addr: yes
Send Resp To Src Port: yes

I also set the RTP Port Min & RTP Port Max so that my NAT router could be set up to forward RTP packets to this device.

This is quite a good posting about setting up Linksys devices to handle NAT (talks about voxalot service but general advice is good) :

The SPA921 config has a "NAT Keep Alive Intvl" which is set to 15 by default, which I'm taking to mean it has NAT keep alives enabled.
