i was trying to test FS with 1 calling party and 1 called party configured in 2 WinSIPs,

the registration to FS is OK for both party, but while making calls, the calling party kept receiving 407 Proxy

Authentication Required response, i tried to uncomment

in internal.xml of sip_profiles and still receiving 407 response.

the FS log keeps on displaying the following DEBUG:

My question is how can i disable FS from asking 407 and/or make the call through?
