We have a customer that is reporting tiny gaps in the voice... not the gaps you would generally hear from packet loss or jitter... I guess I would equate the sound to morse code if you know what I mean.
They said they have had the problem both on internal calls and external calls.
It happens quite a bit apparently -- however we have only been able to replicate it once.
This is a UC540 + SF300-24P + approx 20x SPA502G+500S.
SWP is 8.2.0, Switch is 22.214.171.124.
PSTN connection is a PRI.
The speakerphone is almost always in use when this happens.
If you pick up the handset while the problem is happening, sometimes it goes away, othertimes not.
Has anyone else experienced this? Any troubleshooting tips?
Do you think the issue could be the result of feedback on the speakerphone? For instance the volume on the phone is very loud and looping back in on the call? Also, how did you able to replicate the issue…was it trial and error or was there something specific you did? Also could you very that the SPA502’s are on the latest firmware.
I wonder if it is actually the echo taps kicking in, does it sound similar to like VAD when it happens?
