The <Refer> verb in Telnyx allows you to transfer a phone call to another SIP infrastructure during a TeXML call. You can initiate it at any point during the call. When you use the <Refer> verb, Telnyx will replace the original call with a new call to the external system you specify, effectively transferring the call to that system.
