ISDN is the long-time telephony technology of choice for medium sized business it has provided consistent service, but little flexibility.
With the recent coming of age of Session Initiation Protocol (SIP), telephony is changing for the better, businesses now have the choice to either get more from their existing hardware or completely remove the burden of an on-premise PBX because services can accommodate both scenarios.
The most obvious benefits of SIP are lower cost and increased flexibility over traditional ISDN lines. By switching to SIP, businesses can expect to reduce the cost of infrastructure; a single SIP channel is significantly cheaper than that of its traditional ISDN counterpart.
SIP also enable business to take advantage of more competitive call plans, free internal site-to-site calls and lower rates for national and international calls.
Instead of using a different network infrastructure for voice and data service delivery, SIP provides high quality transmission of voice and data on the same connection, allowing you to consolidate and simplify your network and reduce costs further.
However, cost reduction and hardware infrastructure consolidation are only part of the story.
SIP can be the doorway for businesses to utilise Unified Communications, giving the very latest in collaboration and communication tools. As well as cutting costs, SIP creates a platform for additional benefits and functionality, ranging from remote working to automation.
By enabling productivity tools such as advanced call control, integration into Outlook, call queuing and auto attendant businesses can increase the effectiveness of their people. Telephony starts to work for your business and stops being a necessary burden.
Additional functionality through SIP is delivered directly from the cloud, but integrates with your onsite PBX hardware, removing the need to invest in new hardware, software or in-house skills.
Once SIP is deployed businesses can easily transition users to hosted telephony services, such as WorkLife Talk, giving a truly scalable telephony solution. Businesses on the whole, don’t take a strategic view of their telephony estate.
The cost savings and productivity gains available with SIP allow them to get short term and demonstrable cost savings, while enabling them to use that reserved budget to invest in tools that will help them work and communicate more effectively.
