[SML] intercom search

[George H. Sherlock]

I am starting to look for a possible replacement for our intercom
 system.  We currently have a David Clark wired system and a Telex
wireless.  The 2 do not communicate with each other.  And of course,
as always money is an object..  I have used Clear-com wired and 
Telex wired/wireless at previous employers.  My search has 
brought EarTec to my attention.  I am unfamiliar with them.  
Has anybody used them?  If, so would you recommend them or not? 

Thanks,
