Hi Guys,
We are rolling out some Polycom VVX250 handsets in our organization and may require some Firewall Configs to allow internet traffic to and from the handsets.
My question on this forum is: Under what circumstances would a VVX250 unit need Internet Access? Off the top of my head i'm thinking:
1. Firmware Upgrades
2. Team Integration
3. Register with Online SIP Server
THX....
