Common VoIP Questions Your IT Networking Expert Might Ask You:
- Does the call drop after a certain span of time?
- If so, how many minutes into the call does this happen?
- Is this a system-wide problem?
- Are colleagues experiencing the same issue?
- Is this issue related to a destination you’re calling?
- Do you use the mike mute button?
- Do calls mostly drop when the microphone is on mute?

Possible Reasons For Your Phone Call To Drop
Call Duration LimitCalls can drop suddenly if a call duration limit is placed by the affiliate carrier or the ISP. This is a built-in safeguard to protect users from billing charges. Check to see is if your calls have a short duration limit and make adjustments if necessary or contact your IT networking expert to help check for you.
Talk-Off Might Be The Cause For Your Dropped CallsSometimes, the human voice is improperly detected as a DTMF tone. These control signals are generated when the user presses a key on the phone keypad. “Talk-Off” happens when the remote server/PBX detector is triggered by human speech frequencies. A false trigger of the tone detector might not cause the call to drop each time, but the signal misinterpretation can result in a dropped call or an inadvertent “on hold” call. Talk-Off issues:
- Can occur at any point after the call begins
- May be triggered at the local end when the user speaks
- May result when users attempt to reach a certain destination(s)
- Causes the user to hear a DTMF tone when speaking
Connection Failure May Be The CulpritThere may be one or more reasons that calls are not connecting:
- The Internet Service Provider (ISP) may have routing problems.
- The local exchange on the receiver end might be the problem, disabling the system’s capacity to connect inbound phone calls. This is a common issue during peak demand periods on some VoIP systems.
- The international route has limited negotiation capabilities and the call is dropped.
