Call does not connect

Before reporting a network problem ensure that you are using the correct address to call someone.

Using SIP addresses versus IP addresses

Rather than dialing an IP address (for example, ron@12.134.47.78), remember to use the SIP address (for example, ron@acme.com). The proxy server that routes the call may serve multiple domains and would not know the domain where a user IP address resides.

Domain name

You must enter the domain (for example, @acme.com) if the person you are calling is not in your domain.

Note: The domain name in a user address may not be an Internet domain.

Call is connected but there is no audio

If you are using the handset, check to ensure that the headset button is not activated. The bright red LED light beside the button indicates when the headset option is active. When the headset option is active, and even if there is not headset plugged in, you cannot receive or transmit audio through the handset.
