RFC 2833 and DTMF Relay – Global Knowledge
Note Implementations prior to Cisco Unified Communications Manager Release required MTPs to provide supplementary services for endpoints, but Cisco Unified Communications Manager Release and later no longer require MTP resources to provide this functionality.
DTMF Relay and Interworking on CUBE - Cisco
This new PfR EIGRP mGRE DMVPN Hub-and-Spoke Support feature has introduced the ability to inject routes into the EIGRP routing table, which allows Performance Routing (PfR) to control prefixes and applications over EIGRP routes. This feature also adds support for multipoint Generic Routing Encapsulation (mGRE) Dynamic Multipoint Virtual Private Network (DMVPN) deployments that follow a hub-and-spoke network design.

A. No, the Master Controller does not have a copy of the BGP or static routing tables from any of the Border Routers it controls. The Master Controller does not need to run any routing protocols and is typically not in the data forwarding path.
* It is possible but an administrative nightmare to have a directory number for a number that should be in Lync, this can be done by forwarding all calls to a dummy route pattern across a SIP trunk to the Lync server. This is not recommended due to the added complexity of managing the CUCM and Lync environment. In addition, it would typically require coordination with multiple groups for implementation and troubleshooting.
For more information on supported annunciator sessions with each server platform, refer to the section on Media Resources, in the chapter on Collaboration Solution Sizing Guidance.
Cisco SIP gateways also have the ability to use proprietary Unsolicited Notify (UN) method for DTMF. The UN method sends a SIP Notify message with a body that contains text describing the DTMF tone. This method is also supported on Unified CM and may be used if sip-kpml is not available. Configure sip-notify as the DTMF relay method. Note that this method is Cisco proprietary.
By default, the SIP trunk parameter Media Termination Point Required and the SIP Profile parameter Early Offer support for voice and video calls are not selected.
Branch routers deployed with the Cisco Unified Survivable Remote Site Telephony (SRST) feature can provide multicast MoH in a remote or branch site, with the MoH streaming from the branch SRST router's flash or from a live feed connected to an analog port. Multicast MoH from a branch router via these two methods enhances the Unified CM MoH feature in both of the following scenarios:
DTMF digits can be sent in-band (IB) or out-of-band (OOB), but the most popular, standards-based approach used today is to send DTMF digits in band. In-band relates to the RTP media stream, while out-of-band relates to the signaling path.
