SIP Trunking the Cost Effective Alternative to ISDN

A cost effective alternative to ISDN that gives your business flexibility and business continuity.

What is SIP?

SIP (Session Initiation Protocol) is a technology that allows you to make and receive calls using an IP connection, rather than a traditional ISDN line.
It is fast becoming the standard technology, providing more flexibility, reducing costs, maximising investments and leveraging your IP infrastructure.

Why SIP over ISDN?

For any business looking to move premises, change or upgrade data connectivity or replace their telephone system but at a cost reduction yet still deliver remote working and flexibility SIP is the natural choice.  ISDN is a one-dimension application, restrictive, expensive to deploy and as such faces increasing competition from ergc-sip-trunking-imageasy-to-use, flexible and scalable SIP Trunking.

The benefits of SIP are easy to understand and clear. SIP has far more benefits than ISDN; more flexibility, reliability and value. Businesses that fail to replace and migrate from ISDN will become progressively disadvantaged in terms of service quality,  flexibility, responsiveness and profitability.

Not all SIP service providers are the same – application access, features and most importantly platform reliability are different. SIP can’t work without a data connection, one of the choices to consider is the right access network.

The Benefits of SIP

The lack of legacy integration meant no compromise to our SIP network.  Use our network to deliver calls and services when and how you want them. Plus, logic within our network responds and protects to changes from either loss of service or outage.

As the withdrawal of ISDN has been announced, voice networks move more and more towards SIP.  It is the cost effective alternative to ISDN and delivers far more benefits than ISDN. Please see “The Future of ISDN Communications”
