For Softphones and IP Phones
IceWarp VoIP solution delivers compatibility with most existing SIP phones, hardware or software-based, leveraging the existing investments into IP telephony and allowing users to choose the best communication method when at their desks or when roaming. Presence status and call-to-email address provides an easy way to quickly setup a conference call or speak to their colleagues.
IceWarp WebPhone – Web VoIP Client
IceWarp WebClient includes IceWarp WebPhone, a unique web-based VoIP / SIP client. It delivers the power to speak with others, without the need to deploy & configure hardware or software. IceWarp WebPhone is quickly activated within IceWarp WebClient with one click, and is entirely free to all users of the IceWarp Unified Communications Server.
Desktop Video Conferencing
IceWarp SIP / VoIP Server supports video conferencing in products such as CounterPath's Bria ® or X-lite ® with no need for specialized knowledge. IceWarp's radical level of integration is delivered through one-click deployment, error-free operation and requires no special settings to deploy, making it the ideal solution for enterprises of all sizes.

PBX Integration
By engaging a Voice-over-IP gateway, Skype ® gateway, or router to PBX, companies can enable their FXO analog telephones for Internet calls without additional wiring or change of equipment. Those who already own a different VoIP solution, such as Asterisk ®, will appreciate the rich alternatives of using it in place of the built-in SIP server, configuring it as one of the gateways, or making it accessible for WebPhone users as is.
