Reason Q.850;cause=3

I am trying to understand the following from the ccsip debug. Call seems to go through fine but wondering why i am getting the errors as given below.

Earlier in the day, we had a lot of call drops while calling the 18009264402 external conf bridge number

. Opened a case with ITSP and they said, they were getting the disconnect signalling from our end with the release code of 127. I am trying to understand what is wrong in my side.

What is the IP 100.65.0.154, is that a session target on a dial-peer?, is pings/trace route from the CUBE reaching the destination?

Also would it be possible for you to provide the following debugs for a failed call and the current running config.
debug ccsip message
debug ccsip error
debug ip tcp transcation
debug voice ccapi inout

Please rate if you find this helpful.

Regards,
Aeby

The cause code is saying "No Route to Destination"

LIke the other poster said, configs + debugs and a explanation of how the 100 address fits in will help.

Can you share running configs and following debugs.
debug voice ccapi all
debug ccsip messages
debug ip tcp transactions

Hello everybody,

I had same issue, I only add to trusted list the remote network to resolved it, in my case I used the following config:

voice service voip
ip address trusted list
ipv4 10.2.6.0 255.255.255.0

Regards.
