SIP trunking service is effective business network solutions for small and medium-sized organizations that are looking to cut down on cost, improve customer service and experience and still enjoy quality communication.

In addition to voice calls, SIP trunks also manage multimedia communications such as video conferencing, Facebook Messenger and Skype chats, and other SIP trunking services.
