I'm looking to expand our offerings with headsets that are compatible with VOIP systems, particularly those that work seamlessly with Grandstream phones. We're eager to explore different options that would enhance our product lineup. If you have suitable headset models available, please share their specifications and pricing details. We're focused on quality and compatibility, so any insights on your products would be greatly appreciated. Looking forward to your response!
