Codec list in "LocalConnectionOptions" issue

Hi everybody,

Would you be so kind to help us to set up the PBX properly in order to interact with analog gateways using MGCP?

Here’s the issue:

When connecting Asterisk to an analog gateway using MGCP a sniffer shows codecs shown below

But the gateway supports only a:PCMU;PCMA. Could you please help to correct the settings of the PBX so it could work properly with the gateway?

Thanks in advance!
