Hi,
could anyone please help me setup a configuration of router and modules to manage 15 VoIP SIP channel 4 modems and 200 IP phone?
Is this correct?
Cisco 3845 Integrated Service Router Cisco Unified Call Manager Express EM-HDA-8Fxs (Is a PVDM2-16 required or is it possible to use the DSP integrated in the router?)
What am I missing? Do I need the IP Phone option for the IOS?
TIA for help.
