A PBX to VoIP migration requires careful planning to ensure call quality. Learn how to ready the network, evaluate architecture options and set the right security policies.
Organizations that want to modernize their telephony services and scrap old PBX systems are migrating to voice over IP. But a VoIP migration requires significant planning, from preparing the corporate LAN for voice traffic to setting security policies to protect call data.
Whether completely overhauling your telephony infrastructure or taking a more gradual approach, learn how to prepare your network for VoIP and keep your services secure.
How do I prepare my network for VoIP?
Before migrating to VoIP, organizations need to evaluate several infrastructure considerations. Most important is access to the public-switched telephone network (PSTN). All calls outside of a company require access to the PSTN. VoIP gateways are needed to translate the data between legacy telecom networks and the corporate LAN. Organizations can also deploy session initiation protocol (SIP) trunking to transport voice directly to the PSTN carrier.
Organizations must also prepare the LAN for VoIP to ensure voice calls have enough end-to-end throughput with limited latency and jitter. IT should audit critical network uplinks across the LAN to identify potential areas of congestion. IT should also configure end-to-end quality of service (QoS) policies to ensure voice calls maintain priority on the network.
Endpoints, such as desk phones and softphones, are also important network factors to consider. For desk phones, organizations must address how phones receive power. Most VOIP business phone system Doha Qatar don’t receive power from the phone network, like analog phones, and require an external power source, such as Power over Ethernet. Organizations that deploy softphones as part of a VoIP migration must ensure wireless LAN access points can prioritize voice traffic and have enough coverage to avoid dead spots and bottlenecks.
