ATA 186 - 2nd Port drops calls upon answering.

ATA 186 - Two ports configured. 1st port, no issues whatsoever. But calls to the 2nd Port immediately disconnects upon answering. So far, checked device pool and that looks ok. Checked region settings on CCM4.1 codec, set to G.611.

Thanks

Re: ATA 186 - 2nd Port drops calls upon answering.

What you are probably seeing is a limitation of the ATA. It supports g.711 on both ports but only g.729 on 1 port, port 1 by default. To test this hypothesis you can move the g.729 function to port 2 and see if the problem starts occurring on calls to the port 1. phone. Change the connect mode to 0x90200400 and apply to the ATA and then try the calls to the both phones. If this is confirmed you will have to have the 2nd port in a region that uses g.711 for all calls (after you revert back to the original connect mode).
