[SR-Users] RTPENGINE [ice] Priority collision between candidate pairs

Out of curiosity, I've been skimming the sipwise rtpengine code about this warning and found out that it happens when "__tree_coll_callback()" callback function is called.

Now, the above callback function is present in different places that all reduce to calling "g_tree_insert_coll()" function in ./include/aux.h.

Next, from what i see in "g_tree_insert_coll()" the above callback is **only** called when there is already an old value for the given (key, value) pair. In other words, there is already an "old ice pair" there.

Hope this helps.

Thank you,
