Survivability & Legacy Support: Enabling A Superior All-IP Customer Experience (Part III)

Patton Skydivers

voip-services1OK so we’ve been talking about what features and functions you’re going to need in your SIP-based customer premise equipment (CPE) to ensure your VoIP and Unified Communications (UC) users enjoy a superior ALL-IP experience.

On our list of five, so far we have three down and two to go. So let’s knock out the last two . . .

This post is the final segment in a three-part series about ALL-IP service deployment.
Part I covered the topics Quality of Service (QoS) and Security  >>Read Part I
Part II covered SIP  Compatibility  >>Read Part II


The SIP registrar of a Patton enterprise session border controller (eSBC), can provide a secondary registration point should for instance a hosted PBX become unreachable. This insures the continued operation of the on-premise telephony. Multi-homing, fall-back routing and load balancing can help to increase network up-time.

Legacy Telephony Support

Make your All-IP migration smooth, protect the investment in legacy systems and take time to plan and execute each step along the way. For these reasons legacy telephony interfaces such as FXS, FXO, ISDN BRI and PRI are a key benefit available on the Patton eSBCs.

We are still talking about small and medium businesses (SMBs). The technical challenges are very similar to those faced by large enterprises and service providers. The budget and know-how typically are not.

Therefore a right-sized solution that is affordable and easy to manage is critical. Patton eSBCs are available starting as low as 4 VoIP sessions and scale up to cover the entire SMB segment. Their built-in network analysis and debugging facilities rival the capabilities of expensive dedicated tools and with a very flexible and customizable management concept a turn-key solution can be built for practically any network, customer and application.

The family of Patton eSBCs brings high performance and quality to the customer premise at a price that is affordable for every end user, whether it is a small enterprise of 15 employees, or a larger organization with several hundred users.

That is a SUPERIOR CUSTOMER EXPERIENCE! Whether supporting SIP-to-SIP trunking, Hosted IP Centrex, or legacy PBX-to-SIP solutions, Patton Connects!

  1. Thanks for the 3 posts Doug, a very clear way of explaining our clients the use and need of an eSBC. Nowadays we find more and more PBX’s and SIP Trunks with no eSBC’s in between, and all because what you said in part 1, “it works”, but not as good and secure as it should.
