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

ah - so in your private LAN you are trying to call from a hardphone to a
PC with ekiga ?


This has nothing to do with your router, in this case, the router is
just a switch.

presuming your pc can ping the phone successfully.

i suspect the hardphone needs to register  with a server, I've never
seen one that can directly make SIP calls.

a sniffer trace (wireshark for example) or tcpdump from the pc might be
interesting, just to see what the phone sends, if anything.

if both are registered with a signaling server, and the router is SIP
aware, then the 2 should be able to call each other.

Jānis was exactly correct.
