Cross-regional Multi-Sites Solution

Target client: Medium and large-sized enterprises with nationally branches nationally distributed branch offices.

Is a solution available that offers low cost and high efficiency at the same time? For medium and large-sized enterprises with many branch offices distributed nationally, the Boro SipEverest^TM IP Communication Network Solutions is the best affirmative answer. The solution is designed to greatly reduce redundant expenses and enhance the productivity of the enterprise.

Below is a typical architecture for an existing enterprise network which includes a main office (headquarters) and three branch offices:

A legacy PBX phone system has been installed in the main office, with subscribed E1 trunks connecting into the local services provider. All three branch offices, which are located in different regions of the country, are connected to the main office through a VPN link (an orange dashed line). Two different configurations are adopted by the branch offices: with (Branch Offices #1 and #3) and without (Branch Office #2) local FXO connections.

Base on this legacy architecture, Boro offers the IP Network Communication Solution for the main office and branch offices as follows:

Main office

Expensive legacy PBX systems have often been deployed in the headquarters of many enterprises. It would be a loss to discard such legacy systems completely. Boro has a custom-made solution integrating the legacy PBX that would allow the enterprise to enjoy the advantages brought by the SIPEverest^TM IP Communication Solution will retaining their existing infrastructure. Enterprises may thus introduce new technologies to their network while protecting their existing investments.

At the main office, Boro's solution consists of two BN2000 Qomo IP Communication Servers (IPCS) operating in the primary and backup mode together with one BN1000 Media Gateway. The BN2000 servers provide all of the call processing capabilities of the system. With a HA (High availability) architecture using one primary server and one backup server, communication reliability is greatly enhanced for the main office. The BN1000 Media Gateway enables seamless communications across SIP-based VOIP and PSTN.

Boro's headquarters solution brings the following benefits:

• Simplified wiring for expansion

In deploying new BN300 SIP hard phones and BN400 SIP soft phones, users can use only one type of wiring – either category 5 or category 6 – to connect to the hard phones and to the computers.

• Enhanced call features

With the support of the BN2000 IP Communication Server, each BN300 and BN400 becomes a phone terminal with sophisticated business call features, such as call waiting, call forward, call transfer, voice mail, message indicator, etc.

• Easy maintenance

All Boro's products are designed for simple operation. All provide an administrator web UI and an end-client web UI for convenient management and configuration.

• One number – Multiple Locations

Once the system is set up, new extension numbers can be added along with increase in the number of BN300 and BN400. Any sitting plan changes can be accommodated automatically by the server without requiring PBX reconfiguration or wiring changes. ?An employee may receive calls using the same extension number even when he/she works from a different desk or in a different location.

• Interoperability

Signaling interoperability plays a key role for integration with a legacy PBX. Boro's BN1000 Media Gateway supports not only the common signaling standards such as PRI and MFC-R2, but also the SSI standard which is commonly found in China. With Boro's BN1000 Media Gateway, the new VOIP and the old PSTN networks can be seamlessly integrated into one.

• Dynamic router selection

With the advanced feature “Dynamic Route Selection” provided by the BN2000 IPCS, calls can be intelligently routed through the IP network or the PSTN making use of the best gateway as necessary to minimize cost and optimize the performance of the network. Also, any BN300 or BN400 of the new VOIP network becomes just another extension from the perspective of the legacy PBX system. Conversely, any legacy phone is also just an extension from the perspective of the BN2000 IPCS.

• Extensibility

The power of SIP Everest VoIP technology lays on its extensibility. Extra extensions can be added easily and promptly in the form of additional software licenses. New features such as Instant Messaging, Presence, and Video Conferencing can be extended easily through software upgrade to cope with the growth of the enterprise in the future.

• Productivity

Tele-workers become virtually in their offices regardless of where they are. Using the BN400 soft phone over a VPN connection, tele-workers can be accessed or access one another using extension numbers as if they are all in the same location. Not only are long distance call charges lowered, most importantly, communications between employees become more convenient and effective. Productivity is enhanced.

• Reliability

Every BN2000 IPCS is equipped with a “WatchDog” function which monitors the statuses of various devices and which automatically saves critical processes from system errors. In addition, with a Backup IPCS configuration, full system redundancy is realized.

• High quality

Every product from Boro Networks has undergone rigorous testing, including extended duration stress tests, heavy load tests, long time idle tests etc.

Branch Office with FXO Subscription:

Ever imagine sharing the local FXO subscription with other remote offices? This is made possible with the SIP Everest VoIP Networking solution. In branch offices where a FXO subscription is available, a BN1000 Media Gateway with FXO can be installed through which BN300 SIP Phones and BN400 soft phones in remote offices, including the Main Office, can dial locally to regional PSTN phone numbers. Substantial recurring savings from long distance call charges can be achieved.

With Boro's SIP Everest solution, the main office and branch offices are brought together in virtual proximity. An extension in any branch office is virtually the same as an extension located locally. This implies that close collaboration of virtual teams is now possible. For example, a technical support team can be located at Branch Office #1 while the customer support team is in Branch Office #2. The two teams can carry out conferences effectively using internal extension numbers at anytime. The technical support team can handle customer enquiries directed from the customer support team at the main office, as if the two teams are co-located. Calls can be transferred, forwarded, jointed in conferences freely among remote sites. Less human resources is required and higher performance is achieved.

All of the above advantages are achieved on top of other key advantages of VoIP, including single cabling and easy extensibility.

Branch Offices without FXO Subscription:

Smaller branch offices, where no FXO subscription is available, fit into the overall architecture without any problem. As shown in the figure, no BN2000 IPCS or BN1000 Media Gateway is required in these small offices to connect them with the main office and the external PSTN. BN300 SIP Phones and BN400 soft phones in these small offices can share the BN2000 server in the main office and all the BN1000 Media Gateways in all other offices for their voice services.

Such a simple solution for small branch offices has not compromised the small offices’ potential need of prompt extension. A standalone system with Boro's remote office server and media gateway can be set up within a day or two, after the networking infrastructure is deployed.

Conclusion:

This solution demonstrates the flexibility of the SIP Everest VoIP Networking Solution. The solution offers:

• Seamlessly integration with Legacy PBX

• Easy extension and expansion

• Cost Reduction

• High Performance

Cost and performance, as illustrated, are no longer the two sides of a dilemma. Embrace them at the same time with Boro's Networks SIP Everest VoIP Networking Solution.
