I am currently trouble shooting a frame-relay network with both data and VOIP traffic. One of my remote sites cannot make any VOIP calls across the frame. I am using Siemens HiPath 3550 w/ HG1500 cards which handle the voice g.723 conversion. I am using a Cisco 2611(12.2(5d) router at the remote site and a 3640 (12.2(5d)) at the host site. The routers are prioritizing the voice traffic. During trouble shooting we did a trace route between sites and noticed that between the ethernet and serial interfaces on the host router their was at least a 40-60ms delay . The delay from host to remote network is about 80-140ms. All of the other remotes have a network-to-network delay of less than 50ms. I am thinking the 80-140ms delay is causing problems with my voice calls. I am also wondering why it seems to take so much time between interfaces on my host router. Any thoughts? Below is some of the config info on the router to give a idea of what we are doing.
