XO SIP also interoperable with Digium’s Asterisk Appliance 50, Cisco UC500, Cisco Call Manager, Cisco Call Manager Express and Avaya IP Office.
XO SIP uses SIP signaling and a native IP-based facility to manage all traffic among a customer’s IP PBX system, the XO IP network, and the PSTN. The service eliminates the needs for businesses to maintain multiple access facilities for voice and data services as well as bandwidth-consuming protocol conversions.
XO SIP includes dedicated Internet access with dynamic bandwidth allocation, unlimited local calling, unlimited site-to-site calling for multilocation customers with IPFlex, IP Flex with VPN and XO SIP locations, long-distance calling with choice of calling plans, optional voice compression, and online feature management through the XO Business Center.
Digium’s Asterisk is the world’s most widely used open-source telephony software, and Switchvox is the most widely used premises-based IP PBX based on Asterisk. Switchvox provides a telephony system that integrates with key CRM applications, such as Salesforce.com and SugarCRM through Switchvox’s SMB Switchboard interface.
“Companies that want to integrate voice and data with Switchvox are now assured of full interoperability when they select XO for their IP network,” said Leslie Conway, vice president of global marketing for Digium. “SMBs and solution providers want certified solutions that have been thoroughly tested. Formal XO certification now provides them with a high level of confidence in choosing Digium and XO as a combined solution for their network needs.”
