I have 2 voxalot SIP accounts, one connected on my Siemens C470IP sipphone, and one connected in Empathy or N900. When I call from the sipphone to empathy, it rings, I can answer the call and the empathy's call window appear but it says "connecting" forever (on my sipphone it says the call is running). When calling to N900, I can also answer the call and N900 starts counting the call time, but no sound can be heard on any side.

telepathy-sofiasip resolves the STUN server from the SRV domain record, and this breaks media connectivity for your case, where apparently both endpoints are on the same private network. Try setting the parameter 'discover-stun' to false. Usage of ICE could resolve this problem automagically, if the other endpoint supports ICE as well.
Created attachment 46690 [details] Log with stun turned off Still same issue. I also had that issue when the call comes from outside my network, I don't have logs for that though, would that help you providing them?
Reopening
Some more observations: 1) TURN was disabled on sipphone side, if I enable it both in empathy and sipphone then it works fine. 2) If TURN is disabled both sides it didn't work because I have a VM configured and it used that interface... if I do "ifconfig virbr0 down" then it works. 3) If a friend call from outside to empathy, it doesn't work (see next log attached). 4) If a friend call from outside to sipphone, it works. I've talked with Youness and Olivier, it seems 2 is not fixable. What about 3?

Actually in case 3, my friend did hear me but no the other way. I've checked with wireshark and indeed I'm sending PCMA packets to voxalot's IP but I get nothing back.
