Two questions what exactly is the difference between a port configured for voice vlan for a cisco phone that connects to call manager version 8 versus a a cisco phone on a data vlan that connects to call manager. I see both type vlans connect to call manager and work what are differences and advantages and disadvantages for a port configured as data vlan and voice vlan?
Second question I notice our cisco emergency responder was routing incorrectly 911 when the phone was only on a data Vlan but when we put switchport to voice vlan CER routed 911 correctly. When in the data vlan is was set to default erl instead of its correct one until the port was put the on voice vlan why was that?
