Hello all,
we started using ISDN-SIP gateways where you can specify one digest-id in authentification header for multiple caller ids. Now, there seems to be a problem with security if you don't bind caller-id with ip address or domain. As we cannot know from wich IP (domain) our call will come from we cannot bind it to certain IP (domain). There should be some way to specify which caller-ids (usernames) should relate to auth-id. Similar direction i found in ser admin's guide:
"There may be a need for a more complex relationship between From/To username and digest id. For example, providers with an established user/password database may wish to keep using it, whereas permitting users to claim some telephone numbers in From. To address such needs generally, there needs to be a 1:N mapping between digest id and all usernames that are acceptable for it. This is being addressed in a newly contributed module "domain", which also addresses more generally issues of domain matching for multidomain scenarios."
Still, i didn't found how how could i use domain module for this. What approach other people use in such case?
