[Freeswitch-users] Is my phone on-line?

I want to check to see if a phone or IP provider is on-line. Most systems do this by sending a sip option packet once and a while and seeing if there is a response from the device. Is there a way to do this in FreeSWITCH? __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
