[Freeswitch-users] should FS put/remove the call on hold on update request

Hi all, i've seem some dialog with avaya device and i'm not sure if the behaviour is the correct from fs on update request. I have: FS <--------> remote end invite-----> <---- trying <----- 200ok <----- invite (a=sendonly) 200ok (a=recvonly) ----- > <----- update (a=sendrecv) (1)200 ok ----> <---- bye ack ----> in (1) FS do not change the call flow and it stays in hold. This is the correct behaviour? should it process the update and remove the call from hold, responding wih 200 ok (a=sendrecv) ? I could file a jira if you think is a bad behaviour.. Normally, instead of the update would expect an invite (a=sendrecv)... so i'm pretty sure that it could be a bug in the avaya device. Thanks, António
