A method, comprising: receiving an internet protocol, IP, packet associated with a virtual partition (220, 230, 240; 420) of a plurality of virtual partitions (220, 230, 240; 420) of a session exchange device (100; 200; 400) defined at the session exchange device (100; 200; 400), the IP packet being routed over a media over internet protocol, MoIP, network (170; 270; 465) associated with the session exchange device (100; 200; 400) based on an external IP address value of the IP packet, wherein the external IP address value is usable by a MoIP network connected node to route packets associated with two or more virtual partitions (220, 230, 240; 420) of the plurality of virtual partitions (220, 230, 240; 420) of the session exchange device (100; 200; 400) defined at a session exchange device (100; 200; 400) over the MoIP network (170; 270; 465) to the two or more virtual partitions (220, 230, 240; 420); replacing, after the receiving, the external IP address value of the IP packet with an internal IP address value based on an identifier associated with the virtual partition (220, 230, 240; 420) and based on the external IP address value; sending the IP packet to a portion of an operating system (204, 404) of the session exchange device (100; 200; 400) associated with network processing, wherein the operating system or an application of the session exchange device modifies the packet such that the packet has a different virtual partition identifier and optionally a different internal address value; and replacing, after the sending, the internal IP address value of the IP packet with the external IP address value before the IP packet is transmitted from the session exchange device (100; 200; 400), wherein the packet is transmitted over a second virtual partition. receiving an internet protocol, IP, packet associated with a virtual partition (220, 230, 240; 420) of a plurality of virtual partitions (220, 230, 240; 420) of a session exchange device (100; 200; 400) defined at the session exchange device (100; 200; 400), the IP packet being routed over a media over internet protocol, MoIP, network (170; 270; 465) associated with the session exchange device (100; 200; 400) based on an external IP address value of the IP packet, wherein the external IP address value is usable by a MoIP network connected node to route packets associated with two or more virtual partitions (220, 230, 240; 420) of the plurality of virtual partitions (220, 230, 240; 420) of the session exchange device (100; 200; 400) defined at a session exchange device (100; 200; 400) over the MoIP network (170; 270; 465) to the two or more virtual partitions (220, 230, 240; 420); replacing, after the receiving, the external IP address value of the IP packet with an internal IP address value based on an identifier associated with the virtual partition (220, 230, 240; 420) and based on the external IP address value; sending the IP packet to a portion of an operating system (204, 404) of the session exchange device (100; 200; 400) associated with network processing, wherein the operating system or an application of the session exchange device modifies the packet such that the packet has a different virtual partition identifier and optionally a different internal address value; and replacing, after the sending, the internal IP address value of the IP packet with the external IP address value before the IP packet is transmitted from the session exchange device (100; 200; 400), wherein the packet is transmitted over a second virtual partition.
