What’s exceptional about Grandstream’s GRP2600 carrier-grade IP phones

Grandstream’s GRP2600 series of carrier-grade IP desk phones offers a range of reliable, high-performance IP endpoints to cover virtually any business telephone need, from entry-level phones all the way up to devices for high-call-volume users. In this article we review the five models in the series.

Carrier-grade

Carrier-grade refers to infrastructure that is of sufficiently high reliability for use on a carrier’s or a provider’s network. Carrier-grade is often associated with “five-nines reliability,” which defines a level of reliability where the system is expected to be in a functioning state at least 99.999% of the time. This translates to just over five minutes of downtime per year.

When it comes to IP phones, carrier-grade means that the materials, methods, and manufacturing processes that went into the design and production of these phones has resulted in products that are of high reliability, quality, performance, and efficiency. In short, these phones are expected to function with an extremely small occurrence of faults or failures. This translates into an excellent ROI, an exceptional user experience, and a longevity of both materials and services.

Specifically designed for mass deployments

Conventionally, most of the intelligence or functionality of IP phones is found within the IP PBX, rather than in the endpoints. In contrast, the Grandstream GRP2600 series has been specifically designed with ITSP mass deployments in mind. What this means is that most of the intelligence involved in the telephony features is built into the devices themselves, in their unified firmware. As a result, many of their telephony features, such as three-way conference, internal phone book and call log of up to 2000 records, and personalized music-on-hold and ringtones, are capabilities of the phones themselves, regardless of what brand of IP PBX is used.
