What can SIP Trunking Do?

SIP trunking allows your business to connect its IP-PBX and IP communications systems directly to a SIP service provider, reducing and sometimes eliminating the need for conventional PRI, BRI, ISDN or PSTN voice services.

What is a "trunk" in the context of SIP Trunking?

A SIP Trunk is the logical connection between provider and business defined by the IP addresses, and it could contain as many SIP sessions/ Concurrent Call Paths (CCP) as are needed.

Why do I need SIP Trunking for my business?

SIP trunking is proven to be more cost effective than multiple conventional connections to the PSTN, and can greatly simplify your network through the consolidation of voice and data connections.

Is SIP Trunking secure and reliable?

Yes, SIP trunking has been proven in large scale production environments, and is currently driving cloud adoption of enterprise communications.

Can I keep my current phone numbers?

Yes, we can transfer your existing local and toll-free telephone numbers over to your new MetroLoop services.

Will 911 still work?

Yes, MetroLoop voice services are fully e911 enabled.

Can SIP Trunking grow with my business?
