I have successfully provisioned CISCO phones, YEALINK phones, and now I'm trying my first GRANDSTREAM phones ... with no luck.
For the Cisco, Yealink, and even Polycoms, I used option 66 pointing to my server with http (option 66 ascii --> http://server.address.here/provisioning). Using the same methodology, I cannot get a Grandstream to provision.
it's getting DHCP -- but it's not trying to go to the Thirdlane provisioning server.
Has anyone else had issues like this on Grandstream? Is there anything else to do with a Grandstream? I've pre-provisioned a handset in Thirdlane with the MAC address and I have the template bundle downloaded and chosen for that handset ... but no Joy.
Help is appreciated.
