Firmware upgrade with provisioning url(relative)

[arvind.zapp]

Thanks,
The provisioning address is obtained via DHCP. if there is a mechanism (as i explained), it would be easier to automate the process since we do not need to change config file parameter.
Also current Yealink phone behavior(if it is as you say) is best suited when provision server and phones are in same network. Since provisioning server itself writes the firmware url in our case, it become complex when its behind SBC/Firewall/proxy.In these cases provisioning server may not be aware of FQDN used by phone to reach provisioning server so there is no way to give full url including hostname.

Instead if phone supports the feature, provisioning server could just write relative path. IP Phone would take it up and append it with provisioning server FQDN and send the request.
Relative path works best for load balancing among provisioning servers as well during firmware upgrade.
For polycom, the provisioning server FQDN obtained via DHCP is used for firmware upgrade as well. They just append default firmware file name in it.

Thats why i am looking for it.
