Take a look at the Planet VIP-450 http://www.planet.com.tw/product/product_dm.php?product_id=195&menu_id=3 . We use the VIP-400 (H.323 version), which has lots of flexibility in the dial plan, IDs, etc. You can download the complete manual from the Planet site. Pros: Inexpensive, good voice quality, doesn't crash, excellent hardware reliability, good support for configuration problems. Cons: Many minor bugs and shortcomings (more subtle than your Ovislink and Welltech problems), no support at all for getting these fixed, unless a big customer of Planet happens to experience the same trouble!
