We are in the process of converting all of our remote DS1C connected EPNs at 3 major sites to S8500 and S8300 ESS/LSP. We have found that the faxing that worked with no issues prior to the upgrades now works with intermittent failures. We changed the IP Codec page 2 config from Relay to Pass-through with little change. We then proceeded to undo much of our toll bypass over IP trunking that had some effect, but we still have issues. The problems seem to occur when calls either come in through the main site and traverse the data network to the remote site or vise-versa. Tests done where changes in ARS to use trunking local to the remote site were made resolves outbound issues, but most measures that we are taking to mitigate these problems are opposite of the direction that we are trying to go.
Any help from anyone that would assist us in stabilizing our environment would be greatly appreciated. Thanks!
