Colt VoIP Access eases your migration to a converged, voice and data IP network that connects you to the outside world. VoIP Access makes it possible to have an end-to-end IP network by allowing your calls to be routed (over an IP infrastructure) between your premises and the PSTN.  Colt VoIP Access may also be provided over a dedicated network connection where required.

With Colt VoIP Access, you don’t have to invest in on-site gateways because we provide this functionality within the Colt network. VOIP traffic is passed between your IP PBX and our network, using one of the two best-known standards-based protocols in the industry: H.323 or SIP (Session Initiation Protocol). 

Colt is fully committed to providing connections for your IP PBX based on either SIP or H.323 trunks. While H.323 has proved a popular choice for use in VOIP networks in recent years, SIP is rapidly gaining popularity, and has been widely backed by major IP PBX equipment vendors including Cisco, Avaya, Aastra and Siemens. Colt lets you choose between these protocols, and will help you make the best decision for your VOIP network. Traffic may be sent between your IP PBX and Colt VoIP Access using either of the popular codecs: G.711 or G.729a. Fax and DTMF are also supported through standards based protocols. Supplementary services such as Direct Dial In, presentation and restriction of CLI and Call Forward, and also emergency call handling, are part of the service offer.

Colt VoIP Access supports multiple access mechanisms, including Colt IP VPN (MPLS) and Internet access. Bandwidth can be scaled up as your voice capacity requirements grow.

Call Analyser is a reporting and analysis tool that enables you to create reports that cover all your billed and rated traffic. It's easy to generate user-friendly graphs that tell a simple story and can be presented as an Excel or PDF document to your colleagues or management.

We send you software that can be loaded onto any PC, and each month you can use it to get all the necessary data from our online portal.
