Hi, Zoho CRM has a new add on called PhoneBridge that works with Asterisk/trixbox (apparently). I believe from reading their site about the new feature it requires something loaded onto the server, presumably to allow communication with it. Some more info is here... https://www.zoho.com/crm/call-center/ and the Download Adapter for Asterisk PBX is here (not sure if you need a Zoho CRM account to use this link)... http://zoho.com/crm/1549989/ZohoCRM_CTI_...sterisk_1_4.zip Mark
