Re: [Ekiga-list] Receiving calls with or without a soft PBX?

[Shawn Adams <shawn_adams web de>]

Luigi,

If you aer truly registered successfully on  :xxx.yyy.zzz.ttt server,
then the issue is probably NAT/Firewall.

Once you're registered, the SIP server knows your router's public IP.
Any calls to you are sent to this IP, but the router says "I don't know
port 5060", and drops the frame.

If your router is SIP-aware, or has a SIP ALG, then outbound calls from
your PC work.

You need to either configure your router FW to allow 5060 from public to
private, and the NAT to forward all 5060 frames to the chosen PC on your
private network where ekiga is running.

so - if SIP gateway sends a call to your router's public IP, the router
will say "5060" - send it to 192.168.1.x/24 - your pc where ekiga is
running, and you receive the call.

you could use asterisk, but same problem applies - the asterisk PBX runs
on your private network behind the router, the router NAT/FW will still
drop calls coming inbound from the Internet.

A STUN server may help, recommend using the ekiga "config druid" which
tries to figure out the best method and configures itself accordingly.

Your sip provider might have a STUN server available. Older ekiga
versions one could configure this via the graphical, with current
versions, one has to edit the gconf files.
