[Freeswitch-users] variable_sip_to_tag not set in Leg A for bridged call

Hi, making a bridge call and listening to all events in both legs with esl. i was expecting that CHANNEL_PROGRESS_MEDIA / CHANNEL_ANSWER (on Leg A) would include variable_sip_to_tag since there is already this info (seen in message sent) but we never get this variable to be set in any event. we only get the to_tag on leg A when the call is disconnected or if we put onhold/unhold to force the creation of event. during the call (before forcing hold/unhold) i do a uuid_dump of leg A and i can see the to_tag variable. the channel variable seems to be set only on nua_i_ack and there seems to be no event fired after that. thoughts ?
