How Professional Services Organisations can Benefit from SIP?

The professional services sector is highly competitive and no organisation can afford to stand still. This not only means adapting and developing your business processes, but also the technology that underpins them.

If your organisation is still using ISDN, it could be stifling innovation and reducing your efficiency and competitiveness. SIP can offer businesses many benefits over traditional ISDN. These include:

Speed of deployment:

It can take multiple weeks for new ISDN lines to be ordered and then installed, whereas the lead times for provisioning of a SIP trunking solution can be significantly lower. Once SIP is in place, additional trunks can also be added much more quickly in order to meet increased demand at peak times.


Numbers provided with ISDN are, in the main, geographically defined – unless you pay extra for non geographic numbers. With SIP trunking, you can choose to use the same geographic number, regardless of a site’s location. This is useful for businesses that relocate or those that have multiple sites.


With SIP trunking, your phone system can grow as your organisation grows. It’s easy to increase the number of lines you require and simple to extend your company phone system to new offices.


Many businesses have peaks and troughs when it comes to demand for telecoms capacity. A sales or marketing campaign, or even the time of the year, can see demand greatly increase. ISDN is not always the most flexible or cost-effective option to deal with this type of demand. Even if you can increase the number of ISDN lines to meet the demand, you are left paying for unused channels when demand falls. SIP trunking enables organisations to add more lines as and when they need them, and remove them when call volumes fall. With SIP trunking, you pay for what you use; not for what you rent.

Resilience and Reliability

What would happen if your telecoms system failed, or there was a disaster at one of your sites? The nature of ISDN means that it is vulnerable to a single point of failure – if ISDN lines go down at one site, implementing call forwarding can take hours and can be a costly option. It’s easy to see how this would gravely affect your organisation’s ability to function. Customers, suppliers and contacts would be unable to reach you, leading to frustration at the very least. Reputational damage could be high and the cost to your organisation in lost productivity can be even higher, particularly

if fee-earners are left unable to work. SIP trunking can be provisioned to offer automatic call rerouting to other sites and over additional lines, without call forwarding costs, should disaster strike. With SIP trunking, you can have a robust disaster recovery plan in place as part of your standard service.

High quality

SIP can deliver enterprise-grade voice services over your data connectivity, either a suitable existing connection or alternative provision. With both services delivered through a single connection, your organisation can benefit from additional cost savings.

This combination of benefits means that your organisation is able to elevate the level of customer service you offer, gaining a competitive advantage over rivals still using ISDN and enhancing your reputation.
