Problem with setting up a new NAP

Hi,

I have been trying to configure a NAP to a client's call center. When I point it to an Asterisk Box on their end it answers with no issues however when I attempt to point it to their Primary box (cisco) it does not get responses from them. How to resolve this?

Best Regards,

Hi,

You may not receive 200 OK to your OPTIONS messages if you see your signalling call trace. Please try the following:

Go to NAP - > Select the NAP -> Unclick Filter by proxy port.

if it does not work, you need to check your network and customer network to find first if our OPTIONS messages received by the customer network then you need to check why 200 OKs are not received.

There is nothing to do with ProSBC at this moment. To set that NAP as alive we need to receive 200 OK to our OPTIONS messages.

Best regards,

Thank you.
That change has fixed the issues with the transfers to Cisco.
