eSIP - SIP Trunking

Eclipse, provides a private, secure, reliable, and cost-effective way to access the PSTN through its Eclipse eSIP offering. SIP (Session Initiation Protocol) is an IP to IP connectivity that connects your voice environment to ours; providing you access to the PSTN (Public Switched Telephone Network).

eSIP is a Real-Time Protocol (RTP) used for establishing voice communication on a private data network. The service, eSIP, is delivered over a robust Core SIP network built with redundancy, reliability, QOS (Quality of Service), and security in mind.

Voice traffic is bridged between the customer SBC and the eSIP SBC using private non-routable IPs, ensuring that your voice never traverses the internet, and is not susceptible to outside threats. Each customer SBC will peer with a Toronto SBC and a Montreal SBC, which provides redundant access to the PSTN. The Core SIP network is also built with redundancy between the Toronto and Montreal POPs ensuring the greatest uptime within the core. Trunks are established between the redundant Eclipse SBCs and the Customer SBC. Once the SIP Trunk is established Eclipse can then transport SIP Sessions within the trunk,

sessions can be viewed as a line or channel providing inbound or outbound connectivity to the PSTN. eSIP provides many benefits over traditional legacy PSTN connectivity, such as PRIs, allowing you to save money and stay current with today’s technology requirements. eSIP helps you achieve your business goals by delivering the following voice features;

Basic DID

Basic DID provides a direct inward dial telephone number for your users that will be handled by a third party triage before being passed on to the PSAP when 911 is dialed

E-911

Emergency 911 provides a direct inward dial telephone number for your users that will be handled directly by the PSAP when 911 is dialed.

eSIP Multi-Peer Failover

Delivery of eSIP services to two separate SBCs for redundancy. These SBCs can be local or geographically diverse; in the event one SBC fails eSIP services will automatically fail to the redundant SBC

eSIP Multi-Peer Load Balancing

Provides round robin load balancing between eSIP Peers.

f

eSIP Multi-Peer Overflow

Allows DIDs destined for an eSIP peer to overflow to another eSIP peer when the amount of sessions for that peer have reached their configured amount.

eSIP Peer Redirect to PSTN Telephone Number

Allows DIDs going to Peer A to be redirected to a PSTN number.

eSIP Failover to PSTN Telephone Number

Allows DIDs going to Peer A to failover to a PSTN number if peer A becomes unavailable or does not answer within a given amount of time.

g

eSIP Overflow to PSTN Telephone Number

Allows DIDs going to Peer A to overflow to a PSTN number once peer A reaches a given amount of concurrent calls.
