we want to upgrade our old Avaya telephony system for Cisco Business Edition 6000. We have 2x E1 voice trunks in our office. Does the model C2901-VSEC/K9 (Cisco 2901 UC Sec. Bundle, PVDM3-16, UC and SEC License P) with PVDM upgrade 16 to 64 will cope with the load?
We planning to use on internal segment 2x VG350-144FXS/K9 (144 FXS ports for each) as MGCP gateway and 25 IP-phones with g.711 codec, and no VoIP-to-VoIP on external segment - just 2x E1 trunks. Do we need another PVDM upgrade or may be more productivity platform for the uplink gateway (2901 ISR G2)?
