Cost of PBX

Cost of PBX
Published on:

When it comes to choosing a telephony option, cost is king, especially as free or near-free services, like Skype, become more common in the enterprise. Additionally, management mandates to reduce short- and long-term operational costs have also led to the migration to VoIP.
Organizations get immediate savings with the internet telephony service since the monthly line rate is less than with time-division multiplexing (TDM) systems, including the enhanced features incurring additional charges with standard telephony that is included free with VoIP. Plus, with VoIP, domestic long-distance calls cost little, and international calls will be less. Although these savings must be contrasted with the overall cost of migration to VoIP, there are significant cost reductions with network convergence in which telephony traffic shifts from the dedicated voice network to the data network. Migration to VoIP could also yield hardware savings since IP-based phone systems and handsets cost less than continuing with legacy systems.
It’s important to bear in mind possible hidden costs with network upgrades to support VoIP on LAN and penalties for ending existing contracts with telephony vendors. Enterprises upgrading from legacy telephony to VoIP would need to expand their network capacity to handle voice traffic and possibly add SIP trunks.
Furthermore, new network management capabilities would be necessary to prioritize voice traffic and provide appropriate VoIP security protection. Finally, the organization would need VoIP-specific network infrastructures, such as media gateways and session border controllers (SBCs). Overall, lowering costs can be a solid use case for VoIP but only if the switch is made with these factors in mind.
Use cases
In addition to cost, the need to refresh older PBX systems is driving migrations to VoIP systems. Legacy technology at some companies may be reaching its limits, prompting enterprises to replace aging TDM systems.
Although some businesses may have a telephony environment that works well for its intended purpose, once employees adopt new technologies on their own, legacy telephony usage falls off. In comparison to web-based or mobile voice modes, TDM can no longer support how people communicate. Today, employees rely heavily on other web-based technologies — such as email, chat and video — in which VoIP natively integrates, while TDM does not. VoIP also adds value because it integrates with other data applications over the LAN and enables businesses to migrate their phone management to the cloud. Other definitive benefits to modern IP Telephony PBX PBA Doha Qatar include increased employee productivity — for example, by using visual voicemail and ad hoc conferencing, both of which enable employees to manage missed calls remotely.
