Question on Take back and Transfer (ATT Transfer Connect)

[Jay Schulze]

Hello,

Had a question to exactly how this is seizing the session with SIP. With this service on PRI years ago just using dtmf tones you would hit *8 and it would go back to carrier to initiate the take back. But with SIP I don't believe just hitting *8 from a SIP phone the carrier will know what to do with it. This would just send a notify back to SIP provider. So I guess the best way maybe is to setup a script in UCCE/CVP which would play those tones and send a refer back on that same session?

thanks

You need to issue a SIP REFER to the carrier. CUCM will never initiate a REFER but CVP can:

Make sure that CUBE is not configured to consume the REFER and instead pass it through to the carrier.
