I stumbled upon a simple problem and am looking for an elegant solution to this: I have two clients that want to call eachother exactly in the same moment. What happens of course is that they end up making each one call to the other and have two calls instead of one. what happens is: A calls B --> B accepts B calls A --> A accepts what I want instead is: A calls B --> B accepts B calls A --> A rejects since it figures out its already connected to B. My way of solving this problem is in the callback function on_incoming_call: 1. Get all calls so far by using pjsua_call_get_count<http://pjsip.org/pjsip/docs/html/group__PJSUA__LIB__CALL.htm#g97b0aaeb8f1e6feb8d6794a105abbdc9>(). For all calls - 1, cause the last one is the incoming one do: 2. Check if the corresponding ci.remote_info<http://pjsip.org/pjsip/docs/html/structpjsua__call__info.htm#cc7af5223a21349f5a5a8023cdc39812>.ptr is different then the current incoming new_ci.remote_info<http://pjsip.org/pjsip/docs/html/structpjsua__call__info.htm#cc7af5223a21349f5a5a8023cdc39812>.ptr by matching those 2 strings If they match forbid the call (with 403 message) since I am either already connected to this person, or am currently connecting to this person Else accept with 200 code Is there a more elegant way of doing this, since I dont think the stringmatching is a very good way of checking that fact.
