My personal experience is that I retry 2-4 times, and end up getting through. It doesn't happen often, but does seem to occur as things are starting to get busy on the trunks. That said, I never see blocking on the trunks when I monitor using RTMT, even though utilization is fairly high.<br><br>The DIDs are on a trunk group of 5 Verizon PRIs, and in 2008, were ported by Verizon to a different CO when headquarters moved a few miles down the road.<br><br>Any ideas for things I should look at/for? Should I be calling Verizon, or any of the cell carriers on which the issue was reported?<br><br>Thanks for any suggestions you might offer!<br clear=all><br>-- <br>Dave Wolgast<br>Livonia, NY<o:p></o:p></p></div></body></html>
