I have a tenor ASM-400 with 4 lines FXO and 4 lines FXS, i want to use device as an IP PBX box with the following services :
Customers dial our real PSTN lines and tenor pick up the calls and route them to Digital-Attendant (DA) in SIP proxy server. DA play an IVR sound and tell customer to dial desirable extension number, after customer dial an extension, SIP Proxy will route the call to extension that has an IP Phone.
i want to know that is this possible to provide this service with this devices and softwares ? if yes, please tell me how to configure this setting.
