Manage in real time
and in complete autonomy

From your dedicated interface, you control all your services.
The scalability of the offer over time gives you the possibility to change the number of simultaneous communications according to your needs and to manipulate the DIDs (direct inward dialing) assigned to your Trunk. In case of failure of your equipment or even the connection, a global forwarding ensures the durability of all your calls.

Native or with gateway, compatible with IPBX and PABX

This Trunk SIP solution adapts to all your current telecom equipment. The Trunk Unlimited offer is natively compatible with all IP telephone standards (IPBX) in the market.
If you are equipped with a PABX that does not have SIP connectivity, Sewan will provide a gateway to interconnect the existing platform to your telephone network without any on-site modifications.

Dual-Operator Dual-Technology

Quality management of telephone communications is ensured by Sewan, who provides secure connections with a commitment to service availability
We recommend a redundancy of access connections- with two technologies (SDSL or Fiber + SDSL), two different operators and an automatic rerouting of incoming numbers in case of unavailability of the site.

Routing DID by DID

Number by number, you define the call forwarding you want to set up. You set up rules for permanent forwarding, forwarding on no answer and especially forwarding on no connection, very useful in case of connection or PBX equipment failure. You can also define simultaneous rings for each of the numbers: thus, you can set a forwarding on a number outside Trunk. This first step towards convergence allows you to associate your fixed number with your mobile number.

Always more security

With dual link security you can benefit from different types of configurations, whether in load sharing (active-active) or fail-over (active-standby). Moreover, in order to prevent fraudulent use of your trunk, an anti-hacking mechanism is set up with restrictions by usage profile.
Finally, to guarantee that the use of your trunk is legitimate, Sewan offers IP authentication on its trunks and protection tools using an SBC at the network core.

Customize your services

You can benefit from additional services integrated with the Trunk SIP offers, such as time management, IVR,...
