Cisco Hoot and Holler over IP Configuration Examples
19
Cisco IOS Release 12.1(5)T
Note The connection-trunk connection type is a point-to-point connection, similar to a tie-line
on a PBX network. All voice traffic—including signaling—placed at one end is
immediately transferred to the other.
Note The E&M voice port must be configured for 4-wire operation.
Configuring the Second Router
In router Costello (Figure 4), the E&M phone is connected to voice port 3/1/1. Router Costello uses the
same configuration as Abbott, except for the following differences:
•The virtual interface must be on a different subnet from the first router.
•The IP address in the Ethernet configuration must be different from that of the first router.
•The voice port and slot should match the router’s hardware configuration.

Note The multicast session for this port, shown in the session target command, must match the
multicast session configured on the first router.
The codec configured for this dial peer must match the codec for the dial peer on the first
router.
Both routers must be configured to use the same connection trunk and destination pattern.
