INTRODUCTION This is a technical guide targeted to PBX developers that want to learn the different mechanisms that GRP26XX phones support to get provisioned with other systems. Currently GRP26XX phones can use OPTION66, auto-provision with TFTP, HTTP and HTTPS, Web interface and now with a device auto recognition option that Grandstream called Plug and Play. -

PLUG AND PLAY OPTION First make sure the following guidelines are met: 1- GRP26XX phone should be reset to factory default or out of the box 2- GRP26XX and PBX (support Plug and Play) are in the same local area network Step 1: Sending SUBSCRIBE When the phone boots up, it will start sending a sip SUBSCRIBE message to a multicast IP address 224.0.1.75. -

Step 2: creating configuration file in PBX Per detection of the SUBSCRIBE message, the PBX should display the phone in its device manager tool. The administrator should be able to see the vendor’s name, model, firmware version and MAC address then he can right-click on the device and assign the corresponding account information. -

Step 4: Getting provisioned The phone will immediately open a TCP connection to the URL indicated in the NOTIFY, begins downloading the configuration file and flash it. Phone will reboot to take effect new configuration and a second attempt to download a configuration file will occur. -
Page 7: Remarks
REMARKS All GRP phones will engage the Plug and Play option at boot up, if no NOTIFY is received then the phone will continue with normal provisioning mechanism, meaning checking for an OPTION66 message, If nothing received then go to the indicated URL in the phone’s configuration. The Plug and Play option was developed and verified operation originally with 3CX phone systems.
