* Nehos in no way recommends the use of anything based on Asterisk. We have found Asterisk to be highly unreliable and poorly designed. In the hands of customers who do not know the software very well it tends to be a security nightmare and too unreliable to be considered for business use.

Nehos will not provide support for anything based on Asterisk. For a serious, stable free PABX solution please check out Freeswitch or FusionPBX.
