Features of interest*

Here are some common features you can expect in mobile VoIP apps.

Feature

Description

Call conferencing

Facilitate virtual conferences that connect multiple people remotely. Users can initiate a conference call by inviting participants using a call link or dial-in number. Once everyone joins the call, they can talk and listen to each other simultaneously.

Call routing

Send voice calls to a specific queue based on predetermined criteria. The feature automatically directs incoming calls to the most appropriate agent based on their skills, availability, and location.

Call monitoring

Listen to live phone conversations between agents and customers without being heard by either the caller of the agent. The feature enables intervening into the conversation in critical situations and directly speaking to the customer.

Call recording

Record the audio of phone conversations for quality assurance and training purposes. The feature records both live calls and voicemails to create a searchable repository.

What are the benefits of mobile VoIP apps over desktop versions?

Mobile VoIP apps have become increasingly popular because of their on-the-go communication and collaboration capabilities. Here are reasons to consider a mobile app for your team’s needs.

Benefit

Description

Always connected

Unlike traditional phone lines that restrict communication to a physical location, VoIP apps enable making and receiving calls using existing mobile devices, such as smartphones and tablets. This provides anytime and anywhere accessibility for customer service agents to attend to critical caller issues regardless of their location or working hours. The process ensures that customers are heard and provided with on-time resolution.

Unified communication

Traditional communication often involves juggling separate apps or programs for calls, emails, and messages. Mobile VoIP apps integrate all these functionalities into a single system. This eliminates the need to switch between different apps, saving time and simplifying communication workflows. Mobile VoIP apps often allow screen sharing during calls, streamlining collaboration between customers and agents as they can remotely exchange information and resolve issues.

Cost saving

VoIP calls are made over the existing mobile data plan, unlike traditional phone calls that incur extra fees for long distances. Bypassing cellular network charges can help cut costs, especially for frequent international calls. The application either allows using the existing phone number or provides a free number for calls. This further saves the cost of acquiring and maintaining multiple business lines.

Frequently asked questions when selecting mobile VoIP apps

Here are some common questions you can ask your vendors while looking for the best VoIP software for mobile.

  • What VoIP features are offered by the mobile app?

Mobile VoIP apps come with a variety of features, but they may differ depending on the specific application selected. However, some common features to look for in such apps include, incoming and outgoing calling, call routing, call recording, call monitoring, voicemails, and call history. These features enable VoIP app users to make or receive calls, transfer calls to agents based on urgency or availability, record calls, or access history for training and agent performance assessment. Additionally, the call monitoring feature allows team leaders or managers to silently monitor calls and intervene in the case of unresolved issues. 

  • Does the app integrate with other business tools?

Customer service businesses might use customer relationship management (CRM) or emailing tools. Integrating VoIP apps with these and other existing business applications allows for smooth customer contact accessibility and transfer. Some app integration even allows sending and receiving emails or messages directly from VoIP applications instead of switching between systems. Check the selected VoIP app's integration capabilities and whether it can easily connect with the required applications. 

  • How does the app handle weak internet connections?

With a weak signal, the voice might cut in and out, making the conversation difficult. In severe cases, the call may drop entirely. Check if the VoIP app offers high-definition call quality and prioritizes voice data during calls to maintain even with a weak connection. This might close all applications running in the background. Some apps might attempt to adjust call quality automatically to cope with a weakening connection by reducing audio quality or bandwidth usage.
