Does UC500 support multiple SIP trunks?
What are the maximum number of concurrent calls supported over UC500 SIP Trunks?
The main limit for the maximum number of calls is a function of the WAN bandwidth as that will limit the max number of active calls on the SIP Trunk. In general the UC500 has been tested to the max calls based on user limit on the UC520s & UC540s. On the UC560s it is typically up to 40 active calls max.
