Hi,

I am having periodic sound clicks (2-3 per second) on all FXS of a TDM400P when the remote end is my VoIP provider. However:

- recording the conversation on the asterisk, does not have the glitches, although I can hear them on a real phone.
- My VoIP provider to my VoIP phones through the same asterisk is OK.
- TDM to TDM through the same asterisk is OK.

If TDM to TDM is ok, then it would strongly point towards a problem with perhaps the VoIP provider. This is just shooting off of my hip, but maybe a jitterbuffer issue, like with the phones? I think when Asterisk bridges SIP->SIP calls, it doesn't do any jitter buffering.
If it is a jitterbuffer, then why the recordings (of the same calls I hear the clicks, not other calls) do not have them?

Also, I believe it cannot be an issue of the provider since all ATAs I tested do not have the issue (same provider, same account).
