I'm looking at implementing a SIP proxy server with about 20 units of SPA8000 (full load with 8 analog phones each).
However, i do have some concern on the following justifcation points.
1. Whats the maximum distance a single SPA8000 unit can drive per analog phone? (assuming all 8 ports are being connected to an analog phone each)
2. If i've a delicated lan for the implementation, is QoS settings necessary? (any documentation for the best practices for the SPA8000 ?
