I have a Server Edition 8.1 upgraded to the latest release. I have been battling a choppy voice issue since we installed a month ago.
They are recording calls and archiving to Xima. I listened to some of the calls. Some choppiness is coming from callers dialing into a PRI connected to a BCM at a remote site then the call gets transferred out of the PRI to the IP Office at the site I am at via a PRI.
The other problem is someone will have a caller on the line. They want to transfer to another caller internally. When they do the announced transfer, the conversation between the two internal callers is choppy. Once transferred, the call is fine. So it is good before and after the transfer but not during the transfer. Can anyone explain this?
I used these settings but things did not change.
- Enable GSM Silence Suppression – System>Telephony>Tones & Music>GSM Silence Suppression.
- NoUser Source number CONFERENCE_DSP_TX_GAIN=-3
- Adjust the NLP comfort noise ceiling to be -55dB on the system VCM tab.
- And set VCM > Nonlinear Processor Mode to Silence.
- Reboot after saving these changes
Thanks
