## Memory for SMS and WhatsApp

Agents can now use shared [memory](/memory) across voice, SMS, and WhatsApp, helping them continue conversations with relevant history from any channel.

## RingCX integration

You can now connect [RingCX](/sip-with-ringcx) to Synthflow over SIP, running your agent as an Intelligent Virtual Agent (IVA) in RingCX voice queues. Route voice queue calls to your agent, pass caller context through Workflow Studio, and hand calls back to the RingCX workflow when the session ends.
