zero touch provisioning & firewall - gareth20202 - 10-07-2021 10:40 PM Hi all, How does the zero-touch provisioning redirect service work? Ports etc? We recently installed some phones into a school and the phones would not download the config. Removed them from the site on a normal internet connection and they provisioned fine. Thanks RE: zero touch provisioning & firewall - complex1 - 10-08-2021 01:23 AM (10-07-2021 10:40 PM)gareth20202 Wrote: Hi all, Hi, As far as I know, is there no difference between a zero-touch provisioning and a "normal" provisioning, except the way you do it... provision the phone. Because you can provision the phone at home and not at school, I guess your school router or firewall causes the issue. Make sure the SIP ALG feature of the school router is disabled and try again.

As far as I know the provisioning usually takes place using http/https so normal web ports 80/443. I suspect with a school they have outgoing connections restricted to stop in appropriate sites being viewed and they might even work from a whitelist, and only allow certain known domains or sites to be viewed, so you would need to check with whoever controls that aspect of the network. |
