With every year, SIP is becoming more and more common in unified communication solutions in general, and contact center applications in particular, as companies increasingly recognize the benefits that an all-SIP environment can provide. Legacy contact centers have become expensive to maintain and upgrade and harder to integrate with new and high-value applications. Companies with limited in-house resources can especially benefit from SIP which can support a more dispersed work force including home agents or those working from remote locations.
The SIP based contact center allows companies to leverage new capabilities without pouring more resources into management or IT, infrastructure and applications. These capabilities can be deployed quickly, they are easy to deliver to remote agents and as the companies grow, the solutions can grow with them.
For many organizations, SIP is an integral part of an upgrade, while for others, SIP is part of a telecom cost reduction strategy.
Consider the following migration paths and best practices:
Step 1: Disconnect the PBX from Contact Center trunks
By disconnecting trunks from the PBX, calls can go directly into the contact center, enabling the introduction of new features not supported by the PBX. Data centers can be centralized, routing calls to dispersed contact centers and sending calls to agents that may be company-based, remotely-based or home-based.
Step 2: Computer Telephony Integration (CTI) Migration
Moving to SIP removes some major pain points that have limited contact center efficiency improvements in the past. In particular, it removes the dependency on the PBX. With traditional PBXs, the link between the PBX and the contact center is via a proprietary CTI link. If the CTI link does not support a certain function or does not provide the data necessary for a specific operation, nothing can be done to overcome the limitation. However, in a SIP environment the flexibility is significantly increased because calls can be directed to the contact center application directly.
Step 3: SIP trunking
Consolidation of telephony trunks into SIP trunks saves a considerable amount of money and is far more flexible and scalable. In addition to the estimated cost savings that can be achieved by using VoIP calls, SIP offers the ability to introduce a whole range of additional services to make the customer service operation more effective, ranging from high definition voice to video and more. Contact centers can save considerable expenses by cutting back on toll-free numbers, as VoIP enables click-to-call, which customers can initiate from their PCs or smartphones. Also, with domestic calling being free, VoIP provides another option for agents to make outbound calls to customers, allowing them to be more responsive or even proactive. In terms of enhancing the customer experience, SIP trunking also enables HD audio, providing a high quality call which can be a real differentiator for many companies.
The Key: Seamless Migration
A seamless migration from legacy infrastructures to SIP is key for organizations making the move, many of which are deeply invested in their legacy equipment. In moving to a SIP-based contact center, there is no need for “rip-and-replace” or discarding earlier investments. Customers can choose to convert to this architecture at their own pace and the SIP solution can grow in line with business needs.
Of course, an open architecture like SIP does have some pitfalls: there is no guarantee that two SIP devices will seamlessly operate together out of the box. Basic functions will work but enhanced functions may need to be tested first. AudioCodes provides a complete end-to-end solution consisting of gateways, SBCs, IP phones and other devices that have already been extensively tested and documented in the contact center environment to ensure full functionality out of the box, considerably reducing risk and professional service requirements in a SIP installation.
Ultimately, the result of the move to SIP is a significant reduction of TCO. This is reflected in the considerable savings generated by a reduction of infrastructure costs including the consolidation of telephony trunking and the elimination of separate infrastructure at each location. By virtualizing the resources through the provision of centralized administration, enterprise-wide resources are better put to use, and the company benefits from the flexibility to support multi-channel interactions with customers and a distributed contact center structure which can consist of multiple sites, home agents and hosted services. Additionally, SIP future proofs new media and applications. All this leads to increased agent satisfaction and a better customer experience which also saves costs.
