State of knowledge

August 2020

If the telephone connection is established when using a softphone, but one or both parties cannot hear anything or the voice quality is poor, this is often due to the use of incorrect transmission protocols.

Observe transmission protocols

To connect ProCall Enterprise to the telephone system(s) in use, follow the connection instructions and ensure that the correct codecs and connection protocols are set.

Noise reduction

One way to improve the voice quality can be found in the Audio/Video wizard of ProCall: Here it can be helpful to deactivate the noise reduction under Audio devices for Audio/VideoChat and Softphone.
