ABSTRACT:
Techniques for implementing logical trunk groups with session initiation protocol (SIP) are disclosed. In one particular exemplary embodiment, the techniques may be realized as an apparatus for implementing logical trunk groups with session initiation protocol (SIP). The apparatus may comprise a first network device and a second network device that are configured to exchange SIP signaling messages. Network traffic between the first network device and the second network device may be segregated into one or more logical groups. The SIP signaling messages associated with each logical group may include a Route header that uniquely identifies the logical group between the first network device and the second network device.
