The SPA3xx/5xx IP phone family allows you to configure the phone to support N-way conference calls by using an external conference server.
By factory default, the phones are configured to support 3-way phone-based conferencing.
If you have a conference server, you can configure N-way conferencing on the phone that will initiate conference calls.
Note: The phone will only use one method of conference bridging, either phone-based 3-way or server-based N-way. Once you have configured a Conference Bridge URL, the phone will use server-based conferencing for all conference calls.
Use either of the following ways to configure server-based conferencing on your phone:
- Using the web-UI, edit the Ext N tab > Call Feature Settings > Conference Bridge URL: parameter
- Using a configuration file, edit the appropriate Conference_Bridge_URL_N_ parameter:
<Conference_Bridge_URL_1_ ua="na">MyConference.domain</Conference_Bridge_URL_1_>
