Comparison of call routing methods

Last Updated:

This table compares the features available for the main call routing methods. These call routing methods allow your Zoom Phone system to route inbound calls to a specific phone user or group of phone users. Visit the following articles to learn more about each call routing method:


  • Call delegation is not included in this comparison since it's features are very different from the main call routing methods.
  • Shared line groups are not supported on the Linux desktop client.
  • You can control phone users' access to outbound caller ID numbers that belong to an auto receptionist, call queue, or shared line group.

Note A (shared line groups max membership): Shared line group max membership can be increased to 50. This increased limit must be enabled by Zoom.

Note B (call queues greeting prompt before routing): If the number call queue members is less than 11 or there's a customized greeting prompt, the greeting prompt will play before routing the call. This means the length of the greeting prompt will not be included in the waiting time. If the number of call queue members is more than 10 or there isn't a customized greeting prompt, the default greeting prompt will play at the same time as routing to decrease the waiting time for callers.
