forking increases changes that the call actually gets through, because one of the access networks may not be reachable at the moment. also, if both 3g and wlan is reachable, call comes through many seconds earlier through wlan and is usually also free. i understand that mobile operators don't have incentive to fork the call if one of the legs is free and the other costs money. > And, the UA can make normal (non-outbound) registrations via each of the > two ob proxies.
