Re: AS5300 call connect, but no voice can hear by each other.

Hi ,

You should check your DSPs ( show vfc X board...) it looks like you are facing DSP issue or maybe you have missmatch on ds0 configuration.

Hope it will help you.

Re: AS5300 call connect, but no voice can hear by each other.

I also believe you are also dealing with DSP issues. You can use the following command to view the status of the DSP's from the enable prompt.

test dsp

sh snmp

Here is a output of the sh snmp but if you see any "DSPRM-PLATFM: resource recovery" then you are having DSP issues and the only thing you can do is Call TAC and reload the gateway.

dsprm 1> sh snmp
