I have a Treo 700wx that sometimes has an identical problem. I was able to narrow it down to medical offices and other places that have an older PBX system. I also experinced it once with a person who had a privacy guard on their home phone that prevented a caller ID from being sent. I have no idea how to cure this, but it consistently had something to do with phones or systems that would not disclose a caller ID. Sprint gave me the same "tower issues" excuse and claimed they were doing something to the tower to cure the problem. I am using my PPC 6700 until Sprint fixes this or someone finds a fix. The problem does not occur on my PPC 6700.
