I've been using OZ PRI with DMS and 5ESS protocol variants with very good success. I don't know about the EuroISDN yet. I know that Stefan is working on a lot of Q931 stuff, including timers. It's pretty intense. He's making progress but I don't know how soon he'll be done. Until then I recommend being careful about putting the OZ PRI stack into production without a few precautions. The most difficult symptom to be aware of is having b channels get "stuck" in various states. For example, after hundreds of calls I start to get b channels that are stuck in states like "TERMINATING" or "HANGUP" but never actually make it back to DOWN, i.e. the idle state. The only correlation I can find is that the higher the traffic volume, the more frequently I see these stuck channels. Right now the only cure is to restart FS. Mike and Tony are going to work on an "oz bounce <span>" command but it hasn't trickled up the priority list yet. (I'm sure a quick visit to Tony's paypal account would do the trick!)
