SIP Trunking
Session Initiation Protocol (SIP) Trunking is a way of providing telephone lines using data rather than fixed lines.
It gives you the ability to make and receive calls using IP technology without needing to completely replace your PBX. SIP is the natural replacement for fixed lines and in addition offers greater flexibility and resilience whilst being at a lower price point.

- Fraud protection
- Self-manage portal
- Compliant call recording
- Free Web RTC – “Click to Dial”
Alternatively, you might want a SIP Product with bundled local, national and UK headline mobile minutes that’s feature rich, offering:
- GDPR and PCI compliant call recording

- Call analytics
- End user portal access
Perhaps your business needs both products to truly meet your customers’ needs. At Digital Wholesale Solutions, we are confident we have everything you need, including connectivity, to provide a converged solution to your customers.
