That application looks like a good solution. I can't test it until Monday, but I'll try it and let you know. The drawbacks you mention doesn't seem too inconvenient in my case. Anyway, I started with this cause I thought it was an easy first step, if it gets so complicated I think I'll go forward and put all phones under the control of the PBX. Thank you everybody for your help. -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
