Problem with UPLINK drivers on Skype2SIP

[partysoft]

Hello i will like to report a driver problem, or at least it's how i see it

Here's the description of the problem if someone can help solve this out, i will apreciate it

 

I have installed a SIP server (http://www.brekeke.com/) and configured 2 phones that can ring eachother...and tested with two SIP phones..and the server is OK, good sound no lags. Note that this is done on LAN...and I have a router that goes to public IP (internet)

 

Next i want to receive incoming calls from SKYPE on the SIP phones using the SIP server.

 

I have installed the Skype2SIP solution , with the UPLINK drivers included, everything worked out OK..

Configured Skype2SIP to register to the local LAN sip server and selected in SKYPE to use the UPLINK drivers on audio IN and OUT,

So i have tested and so whenever a SKYPE user calls the selected SIP phone rings...and I can hear the SKYPE user...

THE PROBLEM: THE SKYPE USERS CAN"T HEAR ME, it's like the driver isn't sending any data so SKYPE can't pick up mi voice..so probably no data is sent...

workarround: if i select Audio IN from skype ..to record from microphone attached to the PC.. it works....

 

So i was wandering anyone had this problem, is it a firewall thing? (i mean a saw in the Skype2SIP conf that it has under Options->Network ..Local SIP port to listen on =5070)...and the Allow incoming calls through private networks..

But if i don't use an external SIP server...i think this is not relevant.... (SIP server IP is 192.168.1.x) and SKYPE is raned in the same comp...

And another question will be..for what is the "Local SIP port to listen on =5070" because i already have a SIP server... (this is internal from SKype2SIP? to only route the calls?)

Thank you for any responses!
