[SR-Users] Newly acquired SIP fails authorization from softphone

I am a newbie to the world of VIOP. I am attempting to set up an ATA with SIP. I created a SIP at account iptel.com and received an email confirmation stating "We are reserving the following SIP address for you: sip:larry.baumbach@iptel.org". I tried to testing this address in Xlite but got messages saying: "Account failed to enable. Account Iptel could not be enabled. Verify your user ID, password and authorization name. When I set up the SIP account in Xlite I used: UserID: larry.baumbach(a)iptel.org ( I also tried "larry.baumbach" & "sip:larry.baumbach@iptel.org") Domain: sip.iptel.org Password: my password Authorization name: (I left blank as I did not receive any) I can log into SERweb with the same UserID and Password and access my account. What am I doing wrong? Or is there some kind of wait time before my SIP address is activated? I have spent too much time trying to get this to work on my own. Thanks very much for any help you can provide. -- Larry Baumbach 920.358.8695 larry.baumbach(a)gmail.com
