SRP521 with SPA2102 - Unable to use more than 4 SPA2102

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?

Hi Zahrin,

Have you tried to use diferent SIP source port on each SPA2102?
