I am currently testing the Cisco SPA ATA112 as a music on hold device.
I have found that the device will accept up to 10 calls, which corresponds to what I've read in the product documentation. I have found however that it will only play RTP to up to 4 simultaneous calls, the 5th call is not sent any audio.
I cannot find anything in the product documentation that says that SAS streams are limited to 4 simultaneous calls. Does anyone know if this is a product limitation or is it possible I have something misconfigured?
Thanks
