SIP Lines
SIP is the latest technology allowing voice calls to be made over the internet. Shore Communications uses SIP to provide low cost, ISDN replacement lines that provide the best possible call quality, inexpensively, sometimes at no cost, with the flexibility that comes from using the internet.
Session Initiation Protocol (SIP)
SIP is spilt in to three different yet over lapping technologies; Voice, Text and Video. The G3 mobile network is built on SIP protocols. You may have heard of presence, as in best method of contacting some one, either by voice, text or e-mail, this is also based on SIP, although originally intended for the enterprise application, this has now rapidly moved into the SME market making this technology readily available to the smaller companies as well. Companies such as Microsoft have been actively using SIP as a protocol for a range of applications such as unified communications server.
The Voice World
SIP provides a signalling and call setup protocol for IP-based communications that can support a superset of the call processing functions and features present in the public switched telephone network (PSTN). SIP by itself does not define these features; rather, its focus is call-setup and signalling. However, it has been designed to enable the building of such features in network elements known as Proxy Servers and User Agents. These are features that permit familiar telephone-like operations: dialling a number, causing a phone to ring, hearing ring back tones or a busy signal. Implementation and terminology are different in the SIP world but to the end-user, the behaviour is similar.
SIP is the next logical step in the evolution of voice communications; routing voice calls over the internet provides additional features over and above ISDN and analogue lines. They are more cost effective.
A SIP Trunk is the equivalent of an ISDN channel, depending on your telephony equipment you can mix and match the amount of SIP Trunks and telephone numbers/DDI ranges.
Features Include:
- Cheap line rental
- Cheap DDI ranges
- Any number anywhere. Any geographic
numbers to your phone - You move, so does your number
- Very competitive tariff
- SIP - SIP calls free of charge
Number Provision
We can provide telephone numbers throughout the UK, Europe and the US. A company based in Manchester can be provided with a London telephone number and vice versa; providing you with local presence. SIP trunking is routed over the internet, therefore we point your telephone number to your IP address which can be anywhere in the world.
Number Porting
Moving from London to Manchester and want to retain your London number/s? No problem. We can port your numbers on to our platform and deliver to any IP address in the world. Number porting involves a paper chain; ports can take up to 30 working days from start to completion.
VxDSL (SIP)
VxDSL is a xDSL voice-only service which guarantees network quality for SIP trunks. VxDSL utilises BT ATM coupled with our own MPLS network to provide unparalled levels of service and quality. This has been done before but on expensive private MPLS circuits which isn't feasible for mass market penetration. Shore Communication's VxDSL removes the uncertainty that the internet brings to voice; we don't use the internet, just internet technology. No traffic over the internet.
Features Include:
- No technical knowledge required
- Fully managed service
- No bad call quality
- No traffic over the internet
- DSL connected directly into our MPLS back bone
- No NAT issues
- No need for packet shaping or QOS
- Security levels very high
- Low and consistent latency
VxDSL (site to site)
VxDSL can also be used as a partitioned MPLS network for customers wishing to connect offices together for the purpose of carrying voice and data traffic between offices throughout the UK. Details and prices provided on application.
