Does anyone know how this will affect existing TEHO deployments that utilize the function for 4.x when upgarding to 5.x and on? Using an additional RG doesn't mean alot to you or I but a user with 90+ ICT links with AAR routing backup will probably loose a night or two working that out...

<div dir="ltr" align="left"><span><font face="Arial" size="2">If using gatekeeper for intercluster calls (dial resolution only, not CAC on the gatekeeper itself), does CM distinguish between between a reject due to "the DN does not exist on the remote cluster" versus "insufficient location bandwith" on the remote cluster ?
