Valcom Talkback IP Speakers were compliance tested:
VIP-148L
VIP-160
VIP-172L
VIP-422
VIP-431-DS
When the call button is pressed on a Valcom Talkback IP Speaker, the device initiates a call to a
preconfigured destination that resides on Avaya IP Office, and provides hands-free two-way
communication.
1.1. Interoperability Compliance Testing
The interoperability compliance test plan included feature and serviceability test cases.
The feature testing covered SIP registration, basic calls, display verification, hold/reconnect,
conferences, transfers, media shuffling, audio codec negotiation, and coverage call scenarios.
The serviceability testing focused on verifying the ability of the Valcom Talkback IP Speakers to
recover from adverse conditions, such as a disconnect and reconnect of the Ethernet cable to the
device, and Avaya IP Office reboots.
1.2. Support

2. Reference Configuration
The Valcom Talkback IP Speakers were configured as SIP endpoints that registered with Avaya
IP Office. When the call button is pressed on each of the Valcom Talkback IP Speakers, the
Speaker initiates a call to a preconfigured destination that resides on Avaya IP Office, and
provides hands-free two-way communication. The Valcom Talkback IP Speakers were
configured on the 10.64.20.0/24 subnet, while all the other Avaya IP equipment was configured
on the 10.64.21.0/24 subnet.

6. General Test Approach and Test Results
The feature test cases were performed manually. The call button was pressed on each Valcom
Talkback IP Speaker to test the connection to different destinations on Avaya IP Office, and
manual call controls from the destination were exercised to verify proper interactions with
features such as “transfer”and “conference”.
The serviceability test cases were performed manually by disconnecting and reconnecting the
LAN cables to the Valcom Talkback IP Speakers. Additionally, the Avaya IP Office server was
rebooted to verify the Valcom Talkback IP Speakers were able to properly register and function
normally after the server recovered.
All feature test cases were executed and passed with the following observations:
When shuffling (Allow Direct Media Path) was enabled on Avaya IP Office, calls
involving the Valcom Talkback IP Speakers did not shuffle.
