Hello,
I'd like to explain my scenario and the module I'd like to develop. I am hoping for comments whether there are already modules like that or which modules' API I could use to make the development easier.
Scenario:
I have two domains (A and B) with a Kamailio server in each of them configured as presence servers. The agents from both domains want to subscribe to few resources from domain A.
Idea:
In order to reduce traffic between the domains, the presence server from domain B shall handle the subscriptions internally and use an internal virtual presence-user-agent to subscribe to the resources in domain A.
SIP Messages:
Subscription:
1) Subscribe resource.domain.a, from each user agent ua_n.domain.b
2) 202 OK from kamailio.domain.b
3) If not already subscribed, Subscribe resource.domain.a from kamailio.domain.b with virtual user-agent
4) 202 OK from kamailio.domain.a
(Repeat for each subscriber)
(Subscription has to be refreshed by an internal timer)
Events:
1) Publish resource.domain.a to kamailio.domain.a
2) 200 OK from kamailio.domain.a
3) Notify resource.domain.a to kamailio.domain.b
4) 200 OK from kamailio.domain.b
5) Notify resource.domain.a to each user agent ua_n.domain.b
6) 200 OK from each ua_n.domain.b
(Internally, Kamailio of domain B has to forward the incoming Notify to all locally subscribed user-agents)
I tried using the PUA module but it does not fit all my needs. Now I think I will have to develop my own module in order to achieve everything. Any ideas?
Kind regards
Jan Gaida
PS: Sorry for mailing to both mail-lists. But I was not sure which list was the correct for this topic.
