1. Remote party identification
I create the customer account in A2B - export as SIP friend - and program the customer pbx with the a2b USERNAME and secret code
Yet, that does not work when trying to call any number.
I need to either add host=ipofthecustomer to additional_a2billing_sip.conf
or add a fromuser=USERNAME in the customer original config (but it will not likely be asterisk boxes, so this does not seem very convenient - and I want the simplest setup for the customer)
If I understand the issue correctly, most wholesale switches authenticate via IP and not user accounts. If you want to authenticate via IP, you need to have insecure=port,invite & and IP address of your client/provider in the host field. The username/secret should be erased. See the following post from the knowledgeable jroper:
