I have a PC and a Linksys SPA3102.

I have connected them directly with an etthernet cable (pc address 192.168.0.10, linksys address 192.168.0.1). An analog phone device is connected to linksys (plugged into "Phone" socket).

I turned off PC's firewall.

In Linksys configuration I set: Preferred codec: g711a (PCMA) Register: no; Make call without reg: yes; ans call without reg: yes;

I use pjsua (http://www.pjsip.org/pjsua.htm) to make a call call with arguments

pjsua --bound-addr 192.168.0.10 --no-vad --add-codec pcma sip:192.168.0.1

The analog phone rings but when I answer it no sound is available in any direction.

Any suggestions?

I figured it out. In case anybody encounters the same problem.

SPA3102 does allow calling from WAN only, so I had to plug my PC to "internet" port instead "ethernet" port.
