@Rohan Maradia I'm here to help! To address the SIP trunking issue, I'll need a bit more information. Could you please provide me with the following details: 1. The SIP URI that you're using to connect to VAPI. 2. Any error messages or codes you're receiving. 3. The time when you first noticed the issue. Once I have this information, I'll be able to assist you more effectively. If this is an urgent matter, please ensure that your receiving system is configured to handle SIP REFER messages, as this is crucial for call transfers within VAPI.
