Why we’re increasing prices and what it means for you
As the Irish market continues to embrace digital technologies, the demand for the connectivity & services that we provide is always rising.
To maintain the quality of our network for our customers we’re continually investing in it. This is an expensive activity.
The costs to run and maintain our network continue to increase. This price rise lets us continue to offer both excellent service and a range of products to customers.
While we recognise that no one likes to see their prices go up, we want to continue improving our network, products and services for our customers.
What are my options?
ISDN is fast becoming a legacy service as more and more customers migrate away from traditional copper-based services to IP-based services such as SIP Trunking.
If you are looking to move your voice services to a future-proofed technology with a service provider who can guide you on that migration path, then BT Ireland is the ideal choice, offering the following options:
(a) Global SIP (GSIP)
(b) Domestic SIP (DSIP)
Global SIP (GSIP) is ideal for customers with multinational voice requirements. It enables the customer to use their data network in Ireland and overseas to make voice calls. It is an IP alternative to traditional voice infrastructure like PSTN/telephony and is delivered over an access solution like IP Connect or the internet. This ensures better global communication with their suppliers, customers, and employees.
For customers with domestic business voice needs, and perhaps with legacy on-premises equipment, Domestic SIP (DSIP) enables the customer to avail of all the capabilities of GSIP but exclusively in Ireland over the BT Ireland network rather than the BT Global network. DSIP also offers the option of a managed gateway where the customer requires a PRI presentation into their equipment rather than SIP.
Whatever the requirement, our Voice Specialists will be able to advise on the best alternative for your specific needs.
