We currently have an NEC Aspire phone system. I am looking to add a the 3CX system to a new location to start our conversion to VoIP. Is there a way to be able to get both systems to interact in someway. I am wanting to be able to dial an extension on the NEC from the 3cx and vice versa. The new location will have a PRI for outbound calls so if you know of a good PRI card that I can install on my box and is supported by 3cx i would also appreciate the info. Thanks.
