That actually suggests to me that the problem is in the interface between your ITSP and the PSTN. One way to check this would be to set up a PC on a hub that connects sipXbridge to your ITSP and take a wireshark trace of a call that exhibits the problem. Wireshark has a facility (under Analyze RTP Stream, if I recall correctly) that will let you save the RTP stream as an audio file - do that and then play the resulting audio. If the clicks are not there, they are being introduced somewhere inside your ITSP. _______________________________________________ sipx-users mailing list sipx-users@list.sipfoundry.org List Archive: http://list.sipfoundry.org/archive/sipx-users Unsubscribe: http://list.sipfoundry.org/mailman/listinfo/sipx-users sipXecs IP PBX -- http://www.sipfoundry.org/
