Abstract
In general, techniques are described for performing session layer pinhole management within a network security device. In accordance with the techniques, the network device includes a resource manager module and a Session Initiation Protocol (SIP) module. The SIP module receives a SIP message from a private server, the SIP message requesting a SIP session. In response to the SIP message, the SIP module via the resource manager module opens a pinhole to permit the SIP session and assigns via the resource manager module resources included within the resource pool to monitor each call occurring over the SIP session. The SIP module further determines whether each of the calls has completed based on an session layer characteristic of a subsequent SIP message associated with each call and based on the determination, returns via the resource manager module the resources assigned to monitor each completed call to the resource pool.
