IP telephone technologies work in the place of traditional landline phone networks and telephone systems. With an IP phone, internet protocol and LAN are used to transport phone calls and other information via your ISPís network.
IP telephones work by scanning and identifying the speakersí analogue voice signals and turning that into a digital version of those signals. These digital signals are then transmitted via a broad line in a data format, essentially reconfiguring a phone conversation and directing them via an IP system into the network and then out to be received by the receiverís network internet connection.
While the workings of an IP telephone seem complicated, the use of IP technology can make your business much more efficient by simply operating one internal network to replace traditional phone lines.
IP Telephony PBX PBA Doha Qatar Deployment Models
For single-site model deployment, as the name suggests, the call processing agent will be located at a single site, and a LAN is used to carry traffic internally. Calls beyond the LAN will use PSTN.
Multisite WAN with centralised call processing
With Multisite WAN and centralised call processing, the IP WAN would be used to transport voice data from one site to the other. Call control signalling would also be carried via the IP WAN between the central site and external sites.
This model is ideal if your business has a central site with multiple smaller sites. However, if your business requires full features even in the case of a WAN outage, it might be best to consider alternative models.
Multisite WAN with distributed call processing
Multisite WAN with distributed call processing can be deployed at multiple different sites, and each would have their own call processing agent. Connected to PSTN or IP-WAN or a combination of the two, voice data can be transferred reliably and there is no loss of functionality due to call processing agents at each site. This model is best used for businesses with multiple sites in different regions.
Clustering over the IP WAN
Larger organisations with users across several different sites might consider this deployment model. Each site would be connected via IP-WAN with QoS features. The advantages of this model include having a unified plan, shared line appearances and feature transparency.
