can save you money and help maximise your data network investment as you no longer need separate phone lines.
SIP, which stands for “Session Initiation Protocol”, is the technology used for establishing a voice communication session on a data network (for example over the Internet). A SIP “session” might be a regular VoIP phone call between two participants, or a multi-party conference call. As one of the leading providers of SIP we have extensive expertise in set-up and management of your SIP infrastructure. We also give you access to your own online portal so you can manage moves and charges quickly and without any fuss.
Benefits Of SIP Lines
While the figures vary widely depending on what you currently have and the exact SIP trunk offering you replace it with, savings in the 30% to 60% range are well within the realm of possibility. What’s more, while ISDN2/30 lines are sold in certain increments, such as two or thirty channels, you can order SIP trunks in any size you want. If you’ve got a small office that requires only one or two sessions at a time, you can order and pay for a trunk of only that size.
And should that office grow over time, you can add more circuits to the SIP trunk, again ordering only what you need. No more trying to calculate whether it’s worth moving from ISDN2e to ISDN30 even though you know you don’t need the entire capacity of the larger line.
You can also adjust the size of your SIP trunk to allow for variations in bandwidth requirements, such as to deal with seasonal changes in call volumes. Similarly, you can dynamically vary the amount of bandwidth given to any application based on requirements at any point in time.
SIP is crucial for enabling UC applications including presence and advanced features such as the ability to transfer a call from a mobile phone to a laptop-based soft phone without dropping it. SIP trunks provide the network foundation upon which your firm can deploy such applications.
Because they’re IP-based, SIP trunks are far more flexible than traditional “fixed” circuits such as analogue or ISDN lines. Users can program SIP lines such that if a given user is out of the office, or an entire office is out of commission, the lines roll over to backup sites, phones or devices located anywhere on the company’s network – or at a backup facility. It’s all based on the business rules you set up ahead of time.
