SIP trunks are becoming an increasingly viable option for enterprises wanting to deploy IP-based PSTN access. This chapter highlighted many of the network design and implementation considerations you should work through while planning or installing a SIP trunk for production purposes in your network. Migrating to SIP trunking is a fundamental network change that should be accompanied by the appropriate level of planning and configuration and can require several phases of deployment.
In Chapter 8, another key area of network consideration—interworking and interoperability—is explored in further detail to round out the discussion of network design considerations regarding SIP trunking.
