Sark 500 Auto Provisioning With Yealink SIP Phones

SARK 500 Auto Provisioning with Yealink phones The SARK 500 IP phone system and Yealink IP phones now support fully automated handset configuration using SIP Multicast.

Previously, auto-configuration of IP phones for an on-site PBX relied upon DHCP option 66 to tell the phone where to find its configuration. This was often less than ideal because the installer might not have had control of the customer's DHCP server and even if they had, the DHCP server might not support option 66. In fact the vast majority of DHCP servers built into small routers do not support it. This can cause a major headache when setting up an IP phone system.

The new auto-configuration mechanism implemented on both Yealink phones and the SARK 500 phone system overcomes these problems by not requiring any special configuration or support on external devices.

During boot-up, the phone sends out a SIP packet to a special IP address reserved for SIP Multicast. A SARK phone system listens to this address at all times and will respond, telling the phone where to get it's configuration.

This achieves the same objective as DHCP option 66 but all the functionality is contained within the phone and phone system so there is no need for the customer to change the local network. It will just work automatically.
