Cisco SRST Aggregation

For systems running Cisco Unified CallManager 3.3(2) and later, the restriction of running Cisco SRST

on a default gateway was removed. Multiple SRST routers can be used to support additional phones.

Note that dial peers and dial plans need to be carefully planned and configured in order for call transfer

and forwarding to work properly.

Cisco ATA 186 and ATA 188 Support

The Cisco ATA analog telephone adaptors are handset-to-Ethernet adaptors that allow regular analog

telephones to operate on IP-based telephony networks. Cisco ATAs support two voice ports, each with

an independent telephone number. The Cisco ATA 188 also has an RJ-45 10/100BASE-T data port.

Cisco SRST supports Cisco ATA 186 and Cisco ATA 188 using Skinny Client Control Protocol (SCCP)

for voice calls only.
