when i enable

Hi
i have cisco router with ngx fw

You could try setting canreinvite=no on the trunk for your DID.

Also, what firewall/router are you using? It is likely to be NAT or an ALG (http://www.voip-info.org/wiki/view/Routers+SIP+ALG) on the firewall causing the issue.

I have had similar issues in the past and it turned out to be SIP issues with the firewall. Do you have a router firewall? Have you opened port 5060 for SIP traffic? or better still have you added your trunks ip to have access to your voip switch on the firewall?

Thanks

i have open all the udp port to my pbx
