Make savings and add scalability to your business telephony
For business telephony, SIP Trunking is typically a better choice than ISDN.
SIP Trunking can reduce your call charges and ISDN rental bill, and lets you easily scale up capacity according to your needs.
We can combine SIP with leased lines, WANs and Internet access to deliver an integrated solution.
hSo has multiple connections to the phone network, and soft-switches in multiple data centres to ensure reliability.
If you currently use ISDN, SIP can cut your call costs and ISDN rental charges.
Our telephony experts are always here for you.
hSo has been successfully delivering SIP for more than 10 years. We’re voice technology pioneers.
Your SIP calls can be prioritised over your data traffic by hSo’s QoS-enabled MPLS network.
hSo’s voice range includes hosted or on-site PBXs, ISDN and standard phone lines. We’ll find the best match for your organisation.
We know how important your phone service is to your business. That's why we offer enhanced resilience options that ensure you can still make and receive calls even if your main network connection goes down.
We can use our substantial expertise to achieve a seamless switchover to SIP. For example, we can migrate most existing numbers over to SIP.
SIP calls are typically cheaper than ISDN ones. Unlike most of our competitors, we use multiple SIP wholesale providers, so we can give you the most attractive call rates, plus additional resilience.
