Asterisk Systems

Palo Alto Telecom had been implementing Asterisk and SIP based systems since early 2005 and Asterisk has become our staple PBX offering. Asterisk offers license and subscription free phone system solutions that have changed the game on Nortel, Avaya, Shoretel, Cisco, and the like. Being fully SIP compliant Asterisk can interop with almost any SIP phone, APP, client, carrier, peered PBX, you name it. If your phone solution doesn’t openly support SIP you may want to reconsider the direction of your PBX investment.
