Why VoIP call transfers fail between phone systems

A call transfer may seem simple, but behind the scenes, multiple phone systems must coordinate how to pass an active call to another person or number. They do this through SIP messages, which different vendors may handle in their own ways. When systems don’t agree, calls can drop, callers may hear silence, or transfers may… Continue reading Why VoIP call transfers fail between phone systems

Blind, attended, and broken: What happens when phone systems hand off a call

Call transfer issues can be difficult to diagnose because users rarely report a rejected SIP REFER. Instead, they simply say the call dropped when they tried to transfer it to a colleague. Behind the scenes, the transfer involves several systems that must coordinate the handoff. When something goes wrong, understanding how these systems interact makes… Continue reading Blind, attended, and broken: What happens when phone systems hand off a call

When a transferred call drops: How to troubleshoot SIP interoperability issues

Transfer failures between phone systems usually come down to a handful of common issues. One system may not support the transfer method, SIP headers may get changed along the way, progress messages may not come through, or a firewall may block the signaling. Each issue leaves clues in the SIP logs, making it easier to… Continue reading When a transferred call drops: How to troubleshoot SIP interoperability issues

VoIP capacity planning: The numbers that determine whether your deployment will work

The most common mistake in branch office VoIP planning is treating it as a phone decision when it is really a network decision. The phone system itself is simple. Most deployment problems begin with the network that carries the voice traffic. To get that right, you need to measure the link’s key performance characteristics before… Continue reading VoIP capacity planning: The numbers that determine whether your deployment will work

Planning VoIP for branch offices: What to measure before adding more phones

Adding phones to a branch office seems simple, until calls start dropping during busy periods or audio quality degrades for no obvious reason. Most VoIP problems trace back to decisions made before a single handset is installed: how many concurrent calls the connection can support, whether latency and jitter are low enough to preserve voice… Continue reading Planning VoIP for branch offices: What to measure before adding more phones

Before you deploy VoIP at a branch office, do these five things first

VoIP deployments at branch offices tend to fail for the same handful of reasons, and most can be measured in advance. Five metrics determine whether a phone system will perform well at a given location: concurrent call capacity, WAN headroom, latency, jitter, and packet loss. Testing them before deployment catches problems while they’re still easy… Continue reading Before you deploy VoIP at a branch office, do these five things first

VoIP and VoLTE compared: What each technology does and when each makes sense

For businesses reconsidering their phone infrastructure, the VoIP vs. VoLTE question comes up regularly. Both technologies deliver digital voice calls at lower cost than legacy systems. Where they differ is in the network they rely on, how they perform in different environments, and what kind of mobility they support. Working through those three criteria narrows… Continue reading VoIP and VoLTE compared: What each technology does and when each makes sense

Voice over IP or voice over LTE: Understanding the difference and picking the right fit

VoIP and VoLTE are both modern alternatives to traditional circuit-switched phone systems, but they operate over different networks and suit different working environments. Understanding those differences is the starting point for building a communication setup that actually matches your organization’s needs rather than simply following a trend. What VoIP does and where it works best… Continue reading Voice over IP or voice over LTE: Understanding the difference and picking the right fit

VoIP vs. VoLTE: How to choose the right voice technology for your business

For businesses choosing a phone system, the question is no longer simply how to make and receive calls. It’s where those calls should live: on an internet-based VoIP system or a cellular network using VoLTE. Each has its advantages, and the right fit depends on your team’s needs. What VoIP does and where it works… Continue reading VoIP vs. VoLTE: How to choose the right voice technology for your business
