This chapter is from the book
The following key points were discussed in this chapter:
- Cisco offers a host of solutions for remote sites/smaller sites so that they can connect to and leverage the services from the enterprise network.
- Keeping redundancy in mind, Cisco IOS gateways host the endpoints at the remote site and enable the remote site users to continue using enterprise-grade telephony and collaboration features.
- SRST (and E-SRST) allow the SCCP (and SIP) endpoints to register to local IOS gateways and enable calling within the remote site as well as outside using PSTN or SIP trunks.
