You can integrate Twilio's SIPREC configuration with Google Cloud's Agent Assist. This integration allows Agent Assist to analyze Twilio's audio data.
The architecture
Google Cloud CCAI acts as the session initiation protocol (SIP) recording server (SRS) and Twilio is the SIP recording client (SRC). Twilio has edge locations in Oregon and Virginia, and the Oregon location has Edge servers with a complete, fully qualified domain name that has been configured to communicate with CCAI. Using Twilio's generic SIP recording (SIPREC) connector, you can transmit traffic from the Oregon location to CCAI.
The following image illustrates how the Twilio SIPREC connector transmits voice data from the Twilio telephony SRC to the Google Cloud CCAI SRS.
As part of CCAI, Agent Assist can then send transcripts of that voice data with suggestions back to the Twilio agent desktop using Cloud Run, Pub/Sub, and Memorystore for Redis.
Configure SRS details at Twilio SIPREC connector
Follow these steps to access a Twilio SIPREC connector:
For the SRS, use the following connection string and replace the phone number with the phone associated with your conversation profile. The phone number should be formatted as +1XXXXXXXXXX.
