Configuring Trunk Access Codes
Note
Configure trunk access codes only if your normal network dial-plan configuration prevents you from
configuring permanent POTS voice dial peers to provide trunk access for use during fallback. If you
already have local PSTN ports configured with the appropriate access codes provided by dial peers (for
example, dial 9 to select an FXO PSTN line), this configuration is not needed.
Trunk access codes provide IP phones with access to the PSTN during Cisco Unified CM fallback by
creating POTS voice dial peers that are active during Cisco Unified CM fallback only. These temporary
dial peers, which can be matched to voice ports (BRI, E&M, FXO, and PRI), allow Cisco Unified IP
Phones access to trunk lines during Cisco Unified CM mode. When Cisco Unified SRST is active, all
PSTN interfaces of the same type are treated as equivalent, and any port may be selected to place the
outgoing PSTN call.
Trunk access codes are created using the
access-code
command.
