Come on! Don't be so extreme. There are thousands of Quintum boxes serving very well to their owners.
Well, in that case, tell me this: I've got 4 clients working with Quintum CMS boxes, none of which can go and inter-op correctly with a
simple Cisco AS5350 box. I was wondering why that was, and the only
conclusion I reached is this: Codec Mis-Implementation. The g729 codec
on the Quintum box is marked as g729ab, which means annex a and b complient. Now, if you were to lock the g729r8 codec on the Cisco (this
is what most VoIP carriers use), the Quintum will not be able to negotiate the codec correctly. I've seen this in dozens of cases.
Now, I've worked with various equipments, varying from Vendors to Open Source products, and all I can say is this: If you think of buying a Quintum, don't let the price tempt you, it's not worth it. I've been trying to understand the issues with Quintum, but when every DC comes back with an "unspecified error", it's very hard.
Maybe here you are right, however the "event logger" (the debug sub-system
of Quintum) is IMHO very usefull (specially on CMS). For me personally, it

Well, if you ever managed to inter-op Quintum and a Cisco correctly, I would appreciate getting the exact recepie for that, as I've been battling this for a couple of months now, with no success.
