You should absolutely consider running SIP trunking over Ethernet. One of the primary advantages of SIP trunking is -- unlike legacy telecom services that preceded it -- the IP-based voice service can be delivered over nearly any network access connection.
Metro Ethernet services, one of the more popular flavors of Carrier Ethernet, are well suited to serve as SIP trunk transports. By its very nature, Metro Ethernet provides high bandwidth and low latency network access -- both of which are necessary to provide high-quality and reliable voice calls.
Additionally, Metro Ethernet services support class of service (CoS) designations for traffic management. This allows your service provider to ensure that voice over IP traffic, such as SIP trunking or hosted telephony services, is given the proper priority across the wide area network. CoS, coupled with SIP trunking, offers scalability as your organization's network infrastructure and call volume grow.
Running SIP trunking Metro Ethernet services also allows organizations to consolidate access lines. By consolidating voice and data services to a single connection, most service providers are willing to offer bundled pricing discounts. This can create monthly cost savings of $200 to $1,500 per discontinued line for organizations.
