AW: [Asterisk-Users] Klicking sounds in background

[Jochen Witte]

No - the clocking is OK. It works correctly with different SIP stacks.

When I use voipong to grab the sound, I can hear the klicking in all cases:
when dialing in via PSTN or by IAX / SIP. So the klicking is not on the PSTN
side, but on the RTP side. The mysterious thing  is, that You can only  hera
it, when dialing in via PSTN. Has anybody any idea?
