How can i grab the twilio call SID for the sip call

To grab the Twilio Call SID for a SIP call, you should access the

sip.twilio.callSid

attribute from the SIP participant's attributes. This attribute is available once the call is connected and the participant is active. You can retrieve it using the participant's attributes in your code, as shown in the example below:

participant = await ctx.wait_for_participant()
twilio_call_sid = participant.attributes.get("sip.twilio.callSid")

However, note that the

sip.twilio.callSid

might not be immediately available as it takes time for the call to be fully established. You may need to listen for participant attribute changes to get it when it becomes available. Would you like more details on handling participant attribute changes or any other aspect?

@millions-hair-24956 what should i check in the participants attributes changed event to get the twilio ?

To get the Twilio Call SID from the participant attributes changed event, you should check for changes in the

sip.twilio.callSid

attribute. Here's a basic example of how you can set up an event listener to detect when this attribute becomes available:

@ctx.room.on("participant_attributes_changed")
def on_attributes_changed(changed_attributes, participant):
    if "sip.twilio.callSid" in changed_attributes:
        twilio_call_sid = changed_attributes["sip.twilio.callSid"]
        print(f"Twilio Call SID: {twilio_call_sid}")

This code listens for the

participant_attributes_changed

event and checks if the

sip.twilio.callSid

attribute is present in the changed attributes. When it is, you can access the Twilio Call SID. Would you like more detailed guidance on setting up this event listener or any other related topic?
