<div dir="ltr"><div class="gmail_quote">Hello,<br><div dir="ltr"><div><br></div><div>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.</div>
<div><br></div><div>Scenario:</div><div>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. </div>
<div><br></div><div>Idea:</div><div>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.</div>
<div><br></div><div>SIP Messages:</div><div><br></div><div>Subscription:</div><div>1) Subscribe resource.domain.a, from each user agent ua_n.domain.b <br></div><div>2) 202 OK from kamailio.domain.b</div><div>3) If not already subscribed, Subscribe resource.domain.a from kamailio.domain.b with virtual user-agent</div>
<div>4) 202 OK from kamailio.domain.a</div><div><br></div><div>(Repeat for each subscriber)</div><div>(Subscription has to be refreshed by an internal timer)</div><div> </div><div>Events:</div><div>1) Publish resource.domain.a to kamailio.domain.a</div>
<div>2) 200 OK from kamailio.domain.a</div><div>3) Notify resource.domain.a to kamailio.domain.b</div><div><div>4) 200 OK from kamailio.domain.b</div><div>5) Notify resource.domain.a to each user agent ua_n.domain.b</div>
<div>6) 200 OK from each ua_n.domain.b</div><div><br></div><div>(Internally, Kamailio of domain B has to forward the incoming Notify to all locally subscribed user-agents)</div><div><br></div><div>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?<br>
