Techniques for using sending communication data using a first communication system and a second communication system are described. When a request is received to send communication data, it is determined that sending the communication data includes the second communication system. A request for updated identification information, such as a security token, is therefore sent to the second communication system prior to, for example, determining further account information related to the initiator of the communication and/or an identity of a recipient of the communication. While the request is pending, additional requests for the identification information are delayed. When the new identification information is received, the communication data is sent.
