Also traffic is not an issue. we have tried testing with numerous combinations of codecs on both sides, but did not succeeded. can some advise on this issue. 21st June 2002 at 22:39 #21780 FioGuest Is the cisco system a callmanager? 24th June 2002 at 05:23 #21781 Deepak BGuest No cisco router is used for data and voice communication over lease line 10th July 2002 at 20:31 #21782 MarshallGuest Does the distant phone ring at all?
