I have been working on setting up some VOIP phones for our provider. The phones connect to their provisioning server in order to download the configuration.
If I leave the phone as DHCP, it gets our internal DNS server, which has forwarders set up to Google's DNS servers 188.8.131.52 and 184.108.40.206.
But if the phone gets the IP from the DHCP server, it cannot resolve the domain name domain.jive.com. But if I statically set the IP and DNS servers, only changing the DNS server to Google's, it is able to pull it's configuration.
I also have no problem getting to domain.jive.com from my PC which is on the same subnet with the same default gateway and internal DNS servers.
Any ideas on what could be blocking this phone from resolving the domain name?
