3.4IP Media Constraints

This release includes the following known IP media constraints:

1.Playback to the IP side of LBR Voice Prompts:

•Sending DTMF signals present in the file as RFC 2833 is not supported during playback, i.e., if the file/voice prompt contains digits, they are passed as voice and not as RFC 2833.

•Generation of signals to the IP during playback is not possible.

•If the user wishes to pass DTMF signals present in the file over RFC 2833, or generate in-band signals towards the network during playback, the user must convert the LBR file into an HBR file (G.711 Alaw or G.711 uLaw).
