Phones and Versions Tested

Model Version Notes
GXP2130 IPv6 support is mostly there, but is incomplete. Signalling and Media via IPv6 works correctly, however there are some functions which only support IPv4, for example (experimentally) it cannot connect to a V6 DNS or NTP server. You therefore need to run a dual stack environment, but the bits which are "difficult" with NAT can be pushed through IPv6 without issue. Configuration for A&A was relatively painless

Firewall & Security

  • You will also want to set up firewall rules, as per the VoIP Firewall page.
  • Also see the VoIP Security page for information about securing your VoIP service.
