Your ISDN clocking is slipping (or not sync'd). Your digium PRI needs to clock off the ISDN.
See zaptel.conf on the Wiki and set something like... Span=1,1,... (the second '1' is important.. Ie 'use as primary sync source') http://www.voip-info.org/tiki-index.php?page=Zaptel.conf+span+sintax -- Peter Childs NEC Business Solutions Ltd Ph:61-8-8301-4908 Mb:61-4-0819-7693 IM: pjcinaus (yahoo) -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jochen Witte Sent: Wednesday, 27 July 2005 10:48 PM To: [email protected] Subject: [Asterisk-Users] Klicking sounds in background Hello, I have an IVR with Intel HMP SIP stack, which is a peer behind my Asterisk box (Asterisk 1.0.7, Digium PRI). When dialing in via PSTN, there are klicking sounds in the background, which do not appear, when dialing in via SIP (using Asterisk as pbx). The issue does not seem to be an alaw/µlaw problem. I tried trunking two Asterisk boxes via IAX and then call via two asterisks, but the same effect appears. Whenever there is PSTN involved, I have these klicking sounds, when there is no PSTN, everything works correctly. The setup works great with different SIP peers (others than the Intel...) Anyone has an idea?
