1.3 Development

I can not get the next server to work with my Polycom IP phones.  My phones look for Option 66 for the provisioning server. I have tried several combinations and options on the phone but can not get it to work.  This works fine when using other routers with this feature.  Also, in the latest beta version is has a next server option but will not allow a FQDN like 'provisioning.domain.net'
