	Pros & Cons from Real Users Pros The omnichannel feature is really good, you can build an omnichannel contact center that supports multiple customer communication channels, such as voice, chat, SMS, and email. This enables you to deliver consistent customer experience across channels and provides customers with the ability to contact customer service from any device. Cons I think the cost might be an issue for some businesses, as its more expensive than other contact center solutions, which may make it cost-prohibitive for some businesses. Additionally, businesses may incur additional costs for other additions.
