Having some issues with these 2 equipments.
There's an 8 port switch attached after the router so as to support more devices.
Basically using 4 SPA2102 is OK. Can make in/out calls from the 4 IADs.
However, when the 5th one comes in, all won't work.
All the 5 VoIP IADs are connected to the 8 ports switch.
Any know issues or number of VoIP devices that the SRP521 can handle?
