Two additional ports after 8001 are required for each additional line used. For example, if using a second line, UDP ports 8002 and 8003 are used.

If the firewall restricts incoming connections, you may need to use an outbound proxy to properly receive audio. Ask the VoIP service provider for an outbound proxy address and port number; then enter those values into the ADTRAN IP SoftPhone in the following location:

Settings Menu ->Firewall/NAT ->Firewall Outbound Proxy -><Host>

Users must also set the Use Outbound Proxy field (found with the above setting) to Always.

Port forwarding is not required on a NAT.

Multiple IP Addresses on the Same Computer

If a user’s computer has more than one IP address, the ADTRAN IP SoftPhone may have difficulty choosing the correct address for softphone calls. To set the correct IP address manually, configure the following settings as instructed below:

Settings Menu -> System -> Network -> Auto-Detect IP Address: Unchecked

Local IP Address: [User Computer’s IP Address]

NAT Firewall IP Address: [IP Address of the user’s NAT or firewall]

Another solution is to disable all but one network adapter until after the ADTRAN IP SoftPhone starts.

RPort Attribute

Some VoIP providers do not support the “rport” signaling attribute. Check with the VoIP service provider for details. To turn off “rport,” configure the following setting as instructed below:

Settings Menu ->SIP Accounts ->[User’s Proxy] ->Advanced ->Use rport: Unchecked

Audio Problems

This guide assumes that the computer’s sound and video system are working normally, and that the Tuning Wizard has been run at least once. To run the Tuning Wizard, right-click over the dial pad, and select Tuning Wizard.
