Configure an IOS Media Termination Point for Hybrid Call Service Connect
Out-of-Band (OOB) DTMF is required for DTMF interoperability with Cisco Spark CTI remote devices. If any devices registered to your call control environment do not support OOB, then Unified Communications Manager inserts a software MTP.
To ensure that both audio and video is passed through properly on a call involving TC/CE-based endpoints, you must use an IOS-based MTP with passthrough configured.
The information in this procedure is intended as a generic example for IOS configuration. Your configuration requirements may vary and depend on the IOS version on your MTPs and your call control environment. For further guidance, see the configuration guides for specific IOS versions.
To avoid packet loss, you must use an MTP that supports Real Time Control Transport Protocol (RTCP). See Audio and Video RTCP Passthrough on ISR Gateways for MTP, TRP & RSVP Agents for guidance.
