Source note · SRST on Cisco IOS XE
When a SIP phone registers and matches a voice register pool that has a proxy configured, SRST automatically creates two dial peers: one routing to the proxy and a fallback dial peer routing to the phone.
Checked 2026-09-25
The first dial peer routes to the proxy, and the second (or fallback) dial peer routes to the SIP phone.
