Better Together Over Ethernet; Btoe Firewall Ports - AudioCodes 405HD Administrator's Manual

Better Together over Ethernet

This section shows how to set up the Microsoft Skype for Business feature 'Better Together
over Ethernet' on AudioCodes' 400HD Series of IP Phones.
BToE enables operations to be mirrored on both AudioCodes' IP phone and the Skype for
Business client on the PC/laptop, so that these operations can be controlled from either the
IP phone or the PC/laptop, whichever is convenient to the user at the time, for enhanced
unified communications and optimized enterprise efficiency.
After your IP phone is paired with your Skype for Business client, you can control (from
phone or PC/laptop) operations such as answering incoming calls, making outgoing calls
(click-to-dial), putting calls on hold and resuming them, and making conference calls (see
the User's Manual).

4.10.1 BToE Firewall Ports

Before installing the BToE, make sure the following firewall ports are configured:
TCP port 9999 for communication between the BToE PC application and the phone.

UDP port 9999 for the first steps of automatic pairing.

UDP port 9998 for audio streaming.

Note:
• Port 9999 can be configured with parameter lync/BToE/TcpPortNumber=9999
• The audio streaming is equal to TcpPortNumber – 1
