Well, I think I figured it out. Looks like I only needed the username, password, and the Sip. I used sip.voipwelcome.com for the SIP. So, I'm guessing this is pretty much all I have to do since I can make/receive calls. One thing I noticed though is that when I make an outgoing call to a Verizon Cell, there is about a 10 second lag before I hear a ring. That never happened on the Grandstream. So, not sure if there is another setting I should change to fix that lag.

Otherwise, both incoming and outgoing calls seem to work.

Thanks,

Chris
