I have four PRI's connected<BR>to<BR>> this gateway from the PSTN. I also have a single PRI connected to this<BR>same<BR>> gateway used as a tie line to a Nortel system. I have had no complaints on<BR>> calls going or coming from the PSTN. I have had several complaints on<BR>calls<BR>> to and from the Nortel box. The call could be setup fine and you are<BR>talking<BR>> but the call basically goes silent for about 10 - 15 seconds. The call<BR>does<BR>> not drop only silence. Also if you stay on the call the audio starts up<BR>> again. I don't think it is an IP routing issue because
calls to the PSTN<BR>> work correctly and calls do work to the Nortel it just will stop for a few<BR>> seconds. There are no slips and no errors on the line.<BR>><BR>><BR>><BR>><BR>><BR>><BR>><BR>> ________________________________<BR>><BR>> Disclaimer: This e-mail communication and any attachments may contain<BR>> confidential and privileged information and is for use by the designated<BR>> addressee(s) named above only.
