A method comprising: receiving (301, 5-10) a first signal indicating a request to establish a first prioritized call session, wherein the first signal is received at a call handling device over a first local interface thereof, the call handling device includes a second local interface and an external network interface and is configured to communicate with a local first end device over the first local interface, with a local second end device over the second local interface, and with an external network over the external network interface, and the call handling device is further configured to establish call sessions between the local first end device and the external network and between the local second end device and the external network, wherein each established call session is associated with a different call session identifier from a plurality of call session identifiers associated with the call handling device (5-2, 5-5); determining (302, 5-12), by the call handling device and in response to the first signal, that each call session identifier in the plurality of call session identifiers is associated with a respective pre-existing call session between a respective local end device and the external network; dropping (310, 5-13, 5-14) one pre-existing call session, wherein the one pre-existing call session is associated with a first call session identifier of the plurality of call session identifiers, and wherein the one pre-existing call session is dropped by the call handling device responsive to the determining; and establishing (313, 5-15) the first prioritized call session wherein the first prioritized call session is associated with the first call session identifier. receiving (301, 5-10) a first signal indicating a request to establish a first prioritized call session, wherein the first signal is received at a call handling device over a first local interface thereof, the call handling device includes a second local interface and an external network interface and is configured to communicate with a local first end device over the first local interface, with a local second end device over the second local interface, and with an external network over the external network interface, and the call handling device is further configured to establish call sessions between the local first end device and the external network and between the local second end device and the external network, wherein each established call session is associated with a different call session identifier from a plurality of call session identifiers associated with the call handling device (5-2, 5-5); the first signal is received at a call handling device over a first local interface thereof, the call handling device includes a second local interface and an external network interface and is configured to communicate with a local first end device over the first local interface, with a local second end device over the second local interface, and with an external network over the external network interface, and the call handling device is further configured to establish call sessions between the local first end device and the external network and between the local second end device and the external network, wherein each established call session is associated with a different call session identifier from a plurality of call session identifiers associated with the call handling device (5-2, 5-5); determining (302, 5-12), by the call handling device and in response to the first signal, that each call session identifier in the plurality of call session identifiers is associated with a respective pre-existing call session between a respective local end device and the external network; dropping (310, 5-13, 5-14) one pre-existing call session, wherein the one pre-existing call session is associated with a first call session identifier of the plurality of call session identifiers, and wherein the one pre-existing call session is dropped by the call handling device responsive to the determining; and establishing (313, 5-15) the first prioritized call session wherein the first prioritized call session is associated with the first call session identifier.
