An administrator is configuring a new Cisco UCM with PSTN capabilities. Due to bandwidth constraints, audio compression is used on the codec. DTMF must work as expected because the customer is calling many call centers where the users must select options in the call. Where is DTMF out-of-band in a CCM 12.5 with SIP-based gateway configured?
in the DTMF setting under SIP profile on the Cisco Unified Border Element
in the dial peer on the Cisco IOS router
in regions on the Cisco UCM where the appropriate codec to use is set
in DTMF settings in the audio codec preference list under regions in the Cisco UCM
