4. Technical Presentation Background

SIP (Session Initiation Protocol)• The motivating goal is to create a peer-to-peer connectivity using SIP technology by providing a signaling and call setup for IP-based communications that can support a superset of the call processing functions and features present in the public switched telephone network (PSTN).

• SIP by itself does not define these features; rather, its focus is call-setup and signaling.

• The features that permit familiar telephone-like operations: dialing a number, causing a phone to ring, hearing ring-back tones or a busy signal - are performed by proxy servers and user agents.

• Implementation and terminology are different in the SIP world but to the end-user, the behavior is similar.

5. Network Readiness

It is assumed that the following are currently present at the Clients premises:

1. IP- Phones (SIP Clients) or Soft Phones.

2. Switching architecture (LAN/WAN).

1.Integration of the Clients network devices to Visafone network by establishing a 2MB E1/ IP Link between Rack Centre and Visafone through the nearest PoP or Cell Location. (LS 006 or LS 025)

2.Implement an SIP connection on the established Link between Rack Centre and Visafone.

3.Obtain a and Provision DID block numbers for inward and outward call access.

3.Test connectivity to all the external network from the Rack Centre mini-network.

Visafone Connectivity

• How many centers i.e. Branches and stations are to be connected?

• What other features are required? i.e. making the Client’s network ubiquitous and so on.
