IP authentication in A2Billing using SIP

When you create a SIP enabled account in A2Billing then by default it will be setup to use username/secret authentication. If you want to use IP authentication (where the A2Billing customer uses a fixed IP address to authenticate to you instead) then there are a few settings to change on the SIP account.

This guide was done using A2Billing v1.9.4 and the SIP accounts are created under the “CUSTOMERS/VoIP Settings” menu. Previous versions had a different menu name, but the general idea is the same.

After creating the SIP account check the following –

Change HOST to the IP address of the customer –

a2billing_sip_host

Change TYPE to ‘peer’ –

a2billing_sip_type

Set USERNAME to be blank –

a2billing_sip_username

Set SECRET to be blank –

a2billing_sip_secret
