• In Cisco's troubleshooting technote the authentication URL takes the form http://<InformaCast IP>:8081/InformaCast/phone/auth. in context
• Cisco's troubleshooting technote gives 239.0.1.2 as the InformaCast default multicast address, which can be changed under Broadcast Parameters. in context
• InformaCast's HTTP-based phone busy detection works only when the phone locale is English, while JTAPI-based busy detection works with all locales. in context
• Multicast routing must be enabled between subnets that hold paged phones; the technote mentions GRE tunnels as an option across a WAN. in context
• Phone Web Access must be enabled, at enterprise, profile or device level, so InformaCast can control phones over HTTP. in context
• Cisco's troubleshooting technote activates Cisco CallManager, Cisco CTI Manager, Cisco AXL Web Service and Cisco CallManager SNMP Service for the InformaCast integration. in context
• InformaCast discovers phones through SNMP on Unified CM nodes; if SNMP is not reachable on all CallManager nodes (UDP 161, DNS resolution), phones are not discovered and recipient groups cannot be built. in context
• Cisco's troubleshooting technote says the SNMP community string used for InformaCast must be 18 characters or fewer. in context
