Hi Nathan,

Based on your description you do not want topology-hiding (to simply hide IPs from the end-points), but a mid-presence agent, right ?

Hello,

I have been looking for some examples on how to use the topology hiding module and proxying presence (SUBSCRIBE, NOTIFY, etc.) together, similar to how the mid_registrar module would handle registrations. Does anyone have any examples or suggestions on how to do this?

I have the clients subscribing to the server (through OpenSIPS proxy to another presence server), but I'm not sure how to store the subscriptions and how to route the presence messages. For registrations you can just do save("location"), but is there an equivalent for subscriptions/presence? It seems like the handle_subscribe() function from the presence module wouldn't apply because it's part of a presence server, or can you just use it for storing subscriptions but never publish anything? I don't see a function to look up these stored subscriptions.

Would it be better to just assume that the subscriptions are valid and relay the messages? If so, what is the best way to handle the routing?

Any help or insight would be greatly appreciated!

Thanks,
Nate
