CSIPSimple on Android can not hear the coming calls over 3G

Test

I tried CSIPSimple on my Samsung Galaxy S Captivate and having the same problems with calls through freephoneline.ca over 3G - no audio.  

I tried playing around with some of the settings and the only setting that seems to make a difference is the UDP port.

I had this same issue using freephoneline service at home through a softphone.  The way it was resolved with the help of freephoneline.ca tech support, was that I had to open UDP ports 5060, 5061, 6060, 6061, 13000, and 13001 on my router.  

If not all of these ports were open I only got one-way audio and it seemed to change depending on which port I opened. Since you can only specify one UDP port in the settings of CSIPSimple, I wander if this may be causing the issue.  

Is there a way to somehow be able to specify 6 UDP ports in the settings?Also, could someone may be make a pre-configured account setting for freephoneline.ca in the list of accounts?

The sip settings for freephoneline.ca are actually very simple:

Username: your freephoneline account phone number (1xxxxxxxxxx)
Password: password you get with your sip settings file
proxy: voip.freephoneline.ca
UDP Ports: 5060, 5061, 6060, 6061, 13000, and 13001

That's all that should be needed for it to work.

Love the app, too bad it does not work.

PS.
Works fine over wifi becuase home router has proper ports open.
Not a carrier issue - I'm on Rogers 3G and freephoneline works fine through fring.
