Hello all, I am running CS1000E Rel. 5.5. I have two IBM 306 COTS servers. One Running VxWorks and one running Linux. I have the Xlite 3.0 registered to the SPS as a user endpoint in the NRS and can call a regular Unistem IP phone registered on the same node. When I try to call the Xlite extension though I get fast busy. I did some Dch traces but could not find anything conclusive. I will be performing packet captures to further investigate but was wondering if anyone had any ideas. DNS????
