I have installed a xlite client and if I call from asterisk (via phone attached tdm400p) to xlite, all works fine. Xlite client is also able to register successfully. I followed the configuration instructions as posted on this group. Funny thing is when I try making a call from xlite. I do not see the asterisk even getting an INVITE. I started a SNIFFER and I see xlite sending INVITE requests to an IP address "50.158.110.58". I have no clue where this ip address comes from and why xlite is using this. I checked the configuration on xlite and such an address is nowhere to be found. Thanks for any help.
