assigning a temporary outgoing identity to the end user terminal; and

placing the outgoing communication event, using the temporary outgoing identity, to the destination phone number, in a second network.

2. The method of claim 1 , wherein placing of the outgoing communication event to the destination phone number in the second network is performed through a communication gateway that is selected based on least communication tariff rates.

3. The method of claim 1 , wherein, prior to the placing, determining if a configuration in the communication node disallows terminating a communication event that was intended to be terminated at the destination phone number in the second network, at the communication node.

4. The method of claim 1 , wherein the presence information includes at least one of default configurations and user configurations related to accepting communication events that were originally intended to be terminated at the destination phone number in a second network.

5. The method of claim 1 , wherein the retrieving the user identification includes searching in a list of contacts of a calling user that is stored locally at a calling end user station associated with the calling user.

6. The method of claim 5 , wherein if the locally stored list of contacts does not include the user identification corresponding to the destination phone number, the retrieving the user identification further includes querying a communication server associated with the calling end user station for the user identification.

7. The method of claim 1 , wherein the communication event is one of a voice call or a text message.

8. The method of claim 1 , wherein the configuration of the communication node to receive communication events comprises an indication that components of the communication node are available or functioning properly.

9. A communication system, comprising:

a plurality of end user terminals connected to a first network;

a gateway coupled to the first network and a second network for interfacing the first network with the second network;

one or more communication servers, at least one of the one or more communication servers and at least one of the plurality of end user terminals being configured to place an outgoing communication event to a destination phone number, the placing comprising:

receiving a notification of the outgoing communication event from the one of the plurality end user terminals;

responsive to determining that the destination phone number is associated with a user of the first network, the first network being a packet based communication network:

retrieving a user identification of the user of the first network corresponding to the destination phone number;

retrieving presence information of a communication node in the first network associated with the user, the presence information comprising an indication of the user's availability, and the configuration of the communication node to receive communication events;

placing the outgoing communication event to the communication node associated with the user in the first network based on the retrieved presence information;

responsive to determining the destination phone number is not associated with any user in the first network:

assigning a temporary outgoing identity to the one of the plurality of end user terminals; and

placing the outgoing communication event, using the temporary outgoing identity, to the destination phone number, in the second network.

10. The communication system of claim 9 , wherein placing of the outgoing communication event to the destination phone number in the second network is performed through the gateway that is selected based on least communication tariff rates.

11. The communication system of claim 9 , wherein, prior to the placing, determining if a configuration in the communication node disallows terminating a call that was intended to be terminated at the destination phone number in the second network, at the communication node.

12. The communication system of claim 9 , wherein the presence information includes at least one of default configurations and user configurations related to accepting calls that were originally intended to be terminated at the destination phone number in a second network.

13. The communication system of claim 9 , wherein the retrieving the user identification includes searching in a list of contacts of a calling user that is stored locally at a calling end user station associated with the calling user, wherein if the locally stored list of contacts does not include the user identification corresponding to the destination phone number, the retrieving the user identification further includes querying a communication server associated with the calling end user station for the user identification.

14. The communication system of claim 9 , wherein the configuration of the communication node to receive communication events comprises an indication that components of the communication node are available or functioning properly.

15. A computer readable storage memory comprising stored instructions executable by one or more processors to perform an operation of placing an outgoing communication event to a destination phone number, the operation comprising:

receiving a notification of the outgoing communication event from an end user terminal;

responsive to determining that the destination phone number is associated with a user of a first network, the first network being a packet based communication network:

retrieving a user identification of the user of the first network corresponding to the destination phone number;

retrieving presence information of a communication node in the first network associated with the user, the presence information comprising an indication of the user's availability, and the configuration of the communication node to receive voice communication events;

placing the outgoing communication event to the communication node associated with the user in the first network based on the retrieved presence information;

responsive to determining the destination phone number is not associated with any user in the first network:

assigning a temporary outgoing identity to the end user terminal; and

placing the outgoing communication event, using the temporary outgoing identity, to the destination phone number, in a second network.

16. The computer readable storage memory of claim 15 , wherein placing of the outgoing communication event to the destination phone number in the second network is performed through a communication gateway that is selected based on least communication tariff rates.
