Step 2. Reset and re-configure IP phones

Before migrating IP phones to Yeastar P-Series Software Edition, you need to have your clients complete the following steps to prepare the IP phones for migration.

  1. Reset all the IP phones that need to be migrated.
  2. Re-configure network settings for IP phones to ensure IP phone and Yeastar PBX can communicate with each other over the subnets.

Step 3. Enable Remote Registration for extensions on Yeastar PBX

  1. Log in to PBX web portal, go to Extension and Trunk > Extension, edit the desired extension.
  2. Click Security tab, select the checkbox of Allow Remote Registration in the SIP Security section.
