Have a MBX100 and customer is complaining of intermitten lost orbit or parked calls. When they put the call in orbit 12 and than try to pick up the call it says orbit bin empty and then the call recalls after the recall timer passes. I haven't actualy seen it happen and it doesn't happen often but I beleive my customer when they say it does happen.The customer is holding payment because of this and other MBX issues.
