Presented herein are systems, and methods thereof, that is configured to enter a maintenance mode to isolate itself from its neighbor and to gracefully cause neighbor devices to isolate themselves from the system, as to cause minimal or 'zero' service disruption with its neighbors. The system broadcasts a maintenance-related message, via a standard transport layer, over routing protocols, to counter parts protocols at the neighbor device and waits for an acknowledgement message from the neighbor network devices. The broadcast and acknowledgement, through standard transport layer messaging, ensures that traffic generated by such protocols at the neighbor devices, regardless of manufacturer, are redirected before the system fully enters into the maintenance mode.

Methods and systems for neighbor-acknowledged graceful insertion/removal protocol

A method and system of assigning DSP resources in a voice gateway which first seeks to assign the calls to DSPs on a best fit basis using information in a best fit (BF) pool. If a call can not be assigned on a BF basis, the call is assigned to a DSP based on information in a load balancing (LB) pool. The BF pool indicates which DSPs will be completely loaded by calls using various codecs and which DSPs have calls that have a first channel penalty (FCP). The LB pool indicates the number of calls each DSP is handling.
