AstraQom is one of the most reliable, leading Whistler SIP Trunking Providers.
Our Whistler SIP Trunks offer cost-effective, scalable, and convenient alternatives to ISDN Circuits and analog lines. Compared to ISDN circuits, SIP Trunks can provide far greater functionality at a lower cost. SIP Trunks are scaled and provisioned very quickly.
Whistler SIP trunks from AstraQom eliminates the need for local PSTN gateways, costly ISDN BRIs (Basic Rate Interfaces), or PRIs (Primary Rate Interfaces). You can easily increase or decrease capacity without complicated technical changes.
Our Whistler SIP trunks are Whistler Virtual PRI services that provide you with the benefits of quality PRI circuits.
