We sell both Apsire and Tadiran..and a few others. The Aspire IS a hybrid and it is ok. Networking is weak IMHO but the flash based VM systems are very good. This system when introduced had so many problems that we almost dumped it but, thank goodness NEC got it together and it seems to be fine now. Some notes on the system:

Web based GUI: Not that great IMHO and definately not user friendly unless you have worked on the Aspire.

Ip Phones: Not bad but nothing to write home about and no where near our other products.

Remote Access: Horrible

ACD Reporting/SMDR: This system TOTALLY lacks from the i-series in this regard.

The system is more of a Hybrid than true PBX. Those that have worked on PBX system will notice that the Aspire has alot of features and quite a few pitfalls. For those that want a cheap system that works well..this is your baby. For people that are more into applications such as ACD or networking or large scale IP deployment, this is not the system to cut the mustard IMHO. I have over 100 Aspires in the field and I am a certified tech.
