What is QoS in VoIP?

Quality of Service (QoS) in VoIP prioritizes certain data types, ensuring voice calls are transmitted efficiently. It plays a critical role in maintaining call quality by managing network bandwidth and prioritizing voice data.

What is Regular Call Routing?

Regular Call Routing distributes calls to specified agents in a fixed order, commonly used in hierarchical situations to ensure consistent call distribution.

What is RTP?

Real-time Transport Protocol (RTP) is used for immediate data transfer, such as in live streaming or VoIP calls. VoIP phones utilize RTP for transmitting voice data, but some firewalls might block RTP, causing audio issues in calls.

What is SIP ALG?

SIP Application Layer Gateway (ALG) facilitates SIP connections by modifying packet headers. While beneficial for some services, it often hinders VoIP by removing vital information, leading to issues like connection loss and call drops.

What is SIP Authentication?

SIP authentication involves credentials provided by a service provider to validate a device’s ability to place and receive calls, typically including a username and password.
