vismVoIpDtmfRelay
Module: CISCO-VISM-MODULE-MIB
OID (symbolic): CISCO-VISM-MODULE-MIB::vismVoIpDtmfRelay
OID (numeric): 1.3.6.1.4.1.351.110.3.17.2.5
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: This attribute defines whether the DTMF (Dual Tone Multi-Frequency) digits need to be transported to the other endpoint via NSE(Named Signal Event) packets.
What is vismVoIpDtmfRelay?
This read-write TruthValue defines whether DTMF digits are transported to the other endpoint via NSE (Named Signal Event) packets. DTMF tones can get distorted by voice codecs, so relaying them out-of-band as NSE events instead ensures features like IVR menu navigation or PIN entry work reliably over the VoIP path. For example, if users report that DTMF-based IVR menus fail intermittently on VoIP calls, an admin would verify vismVoIpDtmfRelay is enabled so digits are relayed reliably rather than sent in-band through the codec.
