Do you know if they have a website ?
you might want to check Activemania.com they are Lebanese and work in such domains. i know they have something built on Cisco IP Phones, as for IPhone iam not sure, but you can check with Light and Build as well (
http://www.lightandbuild.com/) they also experience in such needs.
there are many other SOFTWARE companies in Lebanon who do this for you, but i recommend the above two. well known ...
price wise, you need to be able to pay alot, as these things dont come cheap, there is no CONSUMER version, mostly based on clients needs.
