Using ChanIsAvail with the 's' option is supposed to assume a SIP 
channel is occupied if it's in use ANYWHERE under asterisk's wing.   For 
clarification, Dovid, have your poor experiences occurred with the 's' 
or without?  I tell myself I've been meaning to switch away from 
priority jumping into using chanisavail, but always just assumed that 
the 's' options was all I would need to use when it came time....

Thanks!
