Example embodiments provide a method and/or network element capable of joining SIP communication devices into an existing call. According to an example embodiment, a network element may join SIP communication devices by receiving an incoming call from a calling communication device and establishing a connection between the calling communication device and at least one associated communication device in a set of associated communication devices. The set of associated communication devices may be notified of the connection and a conference procedure may be performed in response to an unconnected communication device being activated, such that a multi-way conference connection is established between the calling communication device, the at least one associated communication device, and the at least one unconnected communication device.
