Direct Inward Dialing from Iristel Increases Virtual Local Presence
When businesses need to maintain a slate of local phone numbers in a geographic area even though they operate at a remote location, Direct Inbound Dialing (DID) can direct calls from the PSTN to a customer’s IP PBX (News - Alert), Asterisk PBX, Gateway or Soft Switch. Iristel provides Inbound DID service in Canada for global businesses that require a local presence.
Iristel’s Inbound DID allows enterprises to route calls to individual employee phone numbers without installing individual lines for each employee. To deploy DID, companies will need a high-speed Internet connection; a Softphone-powered device or an SIP/H.323 device; full T.38 fax support; and a compatible CODEC.
Essentially, any service provider seeking to provide a phone service over an IP address has to purchase DID numbers from a competitive local exchange carrier (CLEC), a Level 3 provider or a consortium. DID is often used by calling card companies, inbound call centers, virtual carriers, VoIP carriers and CLECs.
Instead of buying an E1/T1 or analog card, enterprises can simply buy a DID number from a CLEC like Iristel. When someone dials in to the local number, the call will be routed according to the needs of the business. For example, employees can either answer their lines directly or route the calls to an IVR.
In addition to saving money on interconnection, companies will welcome the redundancy of multiple numbers as opposed to a single PSTN connection point. Multiple points of presence ensure speedy disaster recovery because, even when Internet connections or gateways fail, DIDs can be routed to secondary gateways within minutes.
Next-generation service providers can also use DID to select and provision DID terminated to their VoIP gateways anywhere in the world. The high-quality digital signal provided by Iristel ensures call quality, and DID routing ensures the efficiency of call management services.
With Iristel Inbound DID, companies can leverage Iristel’s CLEC status while creating new products and services through both VoIP and SIP. For its DID service, Iristel charges a flat rate and allows unlimited concurrent calls on its multi-channel digital trunk.
