Cisco 3825 - How to configure preferred codec for E1-PRI calls

KK2202

Hi all,

I want to have only g.711ulaw codec supported for all the E1-PRI calls. And calls on other codecs should fail.
Am unable to get that configuration. Kindly help.

Please find attached my current configuration.
Suggest how to configure the preferred codec for controllers E1 for E1-PRI calls.

Any pointers would be highly useful.

Thanks,
KK

I'm fairly sure that E1/T1 cards will default to G711/clear per channel (because of their 64Kb nature) without the need to be configured. I'm not even sure you can change the codec (or would want to) on them.

the gateway is MGCP. just apply it in CCM on the regions.
