Question: When sending a Text-to-Speech (TTS) request, if the SSML script size exceeds the limit for inline transmission in the H.248 command of Mp interface, what should the MRFC use instead to indicate the SSML script to the MRFP?
Option 1: Compress the SSML script to fit within the size limit
Option 2: Send an URI reference to the SSML script
Option 3: Split the SSML script into multiple H.248 commands
Option 4: Convert the SSML script to another format (e.g., VXML)
Explanation: According to specifications, if the pre-processed SSML script size would result in segmentation, the MRFC should use an URI reference to the SSML script instead of sending it inline, allowing the MRFP to fetch the script if needed, ensuring the TTS process can proceed without transmission issues.
