MTP makes video to audio

[noc mcc]

Does inserting an MTP in video calls convert them to audio? Is it mentioned in amy cisco documentation...any one please provide the link.

Hi,

MTP's which support codec passthru are able to handle video calls. The documentation you are looking for is in the following links which says "No video media termination point (MTP) nor video transcoder currently exists. If an audio transcoder or MTP is inserted into a call, that call will be audio only. This is true when the IPVC audio transcoding capabilities is not being used. When the IPVC transcoders are used, you can transcode the audio and send/receive video."

hi Manish, thanks.what is IPVC ?Is it similar to IOS HW MTP or transcoders?

These are high performance multipoint video conferencing and media processing systems, you can check more details here

IOS HW MTP or Transcoders will support video calls with a pass through enabled on them?

What is the difference between transcoder and MTP from point of view of usage?

[Manish Gogna]

Yes, do read the Media resources section of design guide to get an understanding of MTP's and transcoders.

thanks...can we use software transcoders in place of MTPs ?

Hi,

It looks like you are not reading any of the links or the design guide as suggested earlier. You should put in some efforts to understand your own issue in a better way. There is nothing like a software transcoder. Transcoders are always DSP based.
