user busy problem

hello,

I'm using a gateway Cisco AS5350 with the IOS Version 12.4(10), protocol SIP.

When a User is busy, the pstn sends a message busy to the GW but the GW sends a 486 message "busy here" 30 seconds later.

During these 30 seconds, the user receives a dead air on his phone ==>no busy tone.

Do you know a way to fix this problem?

Thanks for your help,

hakim

Re: user busy problem

This problem can occur if output attenuation or input gain are set to non-default parameters on the voice gateway.

To resolve this issue, reconfigure the voice-port on the Cisco IOS? 5350 gateway to default values. Make these changes in voice-port configuration mode:

input gain 0

output attenuation 0
