A method and apparatus for dynamic routing of wireless communications. Mo re particularly, wireless communications are dynamically routed by marking, by a softswitch, every endpoint participating in a call and as the entry for a marked endpoint is updated a message is generated and sent to the softswitch. Upon receiving su ch a message, the softswitch re-computes the necessary new resources for maintaining the call and (i) instructs such new resources to negotiate media transfer, (ii) after receiving an acknowledgement from the new resources, transmits appropriate call initiatio n messages to such resources; and (iii) transmits call release messages to the prior, i.e., old, resources supporting the call. Advantageously, selection of the requisite resources to participate in a particular is driven by the knowledge of the communications network topology. As such, resources are selected which are topologically closer to the endpoint thereby increasing the efficiency of the network resources on a network-wide basis.< /SDOAB>
