La téléphonie IP, Autocom & IPBX par Koesio

IP telephony, Autocom & IPBX

Voice over IP has revolutionized corporate telephony, simplifying the deployment of your corporate telephony network.

With an IPBX, all you need to make calls is access to your Internet connection. Your telephones are directly connected to this PBX, which transports voice over the web, and via your local computer network.

This means you can share costs and easily deploy new lines as and when you need them. You can also pool your telephony across your various sites, using a single infra scheme.

100% virtual IP telephony

With softphone solutions, you’re no longer obliged to use a telephone system; you can directly integrate the telephony solution on your PC.

Enter the world of unified communications, with voice, e-mail and chat channels integrated directly into your computer telephony application (softphone).

A new dimension for your communications.

Voice subscription with Trunk SIP service

Trunksip is the technology that replaces analog and digital telephony, enabling voice to be routed over the public telephone network.

Calculated on the basis of the number of simultaneous calls you wish to make, it is offered in pairs and requires a 100kb throughput provision for each channel. This means, for example, that for 10 simultaneous calls, you need to dedicate 1MB of your Internet link to VOIP.

Hence the importance of pairing it with an SDSL or fiber-type Internet offer, with a dedicated speed for voice, to maintain constant quality in your communications.

This solution also enables you to benefit from free calls between your company’s remote sites and advantageous rates to the outside world.
