The provider must allow 999 calls over their network; this has been an Ofcom requirement for some years now. Where the VoIP service is mainly in use at a fixed location, the Caller Location Information should also be included. The provider should allow registration of on-net and off-net DIDs and may have additional features such as an alert via email or SMS when a 999 call has been dialled.
Transparency with re-selling and carriers
In order to provide the widest possible cayman islands whatsapp number data coverage, providers partner with other providers and carriers worldwide. The arrangements can become complex, making it hard to understand exactly which carriers are involved. The provider should be transparent about who they are partnering with and for which regions.
Backup
For an ITSP, engaging with a client with their own switch is feasible, but requires clear contractual terms. If the client’s switch breaks down, it needs to be clear who is responsible and what the backup arrangements are. The provider can help by offering a backup or forwarding service for the DIDs. Calls can then be re-routed to the client’s mobile phones or answering service.
Reporting
Running a profitable business requires detailed reporting of all costs so that profit and margins can be calculated. Strategically too, reporting can highlight areas where the business can gain competitive advantage. The DID provider has all the information available regarding usage; it’s essential that they can deliver this information in a form that the business can use.
