I've never used a softphone and am trying X-Lite v-3.What softphones would you recommend? The reason why I'm asking is--

My protocol analyzer is seeing a few hundred frames between my machine and amazonaws.com before the first SIP frame or the initial DNS query for *.voipwelcome.com.

PROTOCOL HTTP with: compute-1.amazonaws.com
PROTOCOL SSL tunnel with: https://counterpath.s3.amazonaws.com
PROTOCOL SSL tunnel with: s3-1w.amazonaws.com

I have no idea what information is being sent/received in the tunnels.
Some of the certificate info is:
=========================
S
DigiCert Inc
www.digicert.com
DigiCert Global CA0
US
Washington
Seattle
Amazon.com Inc.
*.s3.amazonaws.com

Tnx a lot.
