Cisco ATA 186 Issue

[ysanadiga01]

Hi there,

I configured both ports of a Cisco ATA 186 connected to CM 4.1. On both ports I've configured Analogue telephones. The telephone working on the 1st port works fine, but the phone connected to 2nd port will ring once and the connection is broken. If I change the ports then, the phone on the first port will work fine but the phone connected to the 2nd port got the same issue.

I hope someone can help me sort out this issue.

Thanks.

Hi Sana,

Just a thought here, but the second port of an ATA only supports g.711;

Have a look at these two good posts that relate to this type of issue;

Hi Rob,

Thanks for your reply. I studied both documents. It means that I can configure Port 1 with G.729 region and the other port (Port 2) will automatically use G.711 Codec?

After weekend I will go and use connect a fax, which is configured to use Region with G.711. I hope this will solve my issue otherwise I will come back here.

Thanks.
