We have a M3903 phone, early on this phone the user could answer one call, and if at the same time the user receive another call the user could put in wait the first call and answer the second call, actually the user say that she dont can realize this operation, i think that in past time the configuration on conmutador opcion 11 c was ok, but then this configuration was replace with a bad configuration, i think that the configuration for this phone was overwrite with the configuration of the other phone that do not have the same configuration of the first one phone, but a dont know what setting i need to move.
