Network – Netgear Router Port Forwarding and Port Triggering | AT&T Office@Hand
Article #5205

How do I set up port forwarding or port triggering on my Netgear router?

Port Triggering and Port Forwarding are NAT/firewall-related features and functions. These features are available on most, if not all, SOHO (Small Office Home Office) routers; they are usually not available on higher-end routers or firewalls.  Port Triggering and Port Forwarding, DO NOT contribute to QoS/call-quality improvements.  

Set up Port Triggering or Port Forwarding only if:

  1. Security changes were made to your network configuration, or router, and are now unable to make calls using the AT&T Office@Hand phone system, or experiencing one-way audio.  This is due to connectivity issues to/from AT&T Office@Hand’s SIP servers.
  2. You installed a new router. After confirming that internet connectivity is OK, and the phone is powered on, and you still are unable to make calls using the AT&T Office@Hand system, or experiencing one-way audio, then port triggering or port forwarding may be necessary.

Follow the steps below to proceed:
