SIP Refer to FXO hook flash

[John Watkins]

Hello, we are using and cisco 2921 as an analog to SIP gateway. Calls from an very old key system come into the 2921 via an FXO port and are PLAR'd to the an Voip Dial peer configured with SIP to an IVR application. IF an user dials 0 to go to an operator this send a SIP refer back to the 2921 with the extension to refer too, the 2921 creates a new call leg and "hair pins" the call using two FXO ports. I would like to know if there is a way to correlate and SIP Refer to analog hook flash, if not possible are there other creative ways to acheive this with an intercepting TCL or VXML script?

Hi, John,

I recommend you post this question to the Cisco Support Community (https://supportforums.cisco.com/index.jspa) where our Cisco technical support experts provide assistance. This community does not provide technical support and is not staffed with technical support experts, so I think you will achieve better results by posting to the Support Forum.
