Hookflash transfer support from FXS port on H.323 gateway?
We have the following:
Analog device ---fxs—gateway---h323—ccm 6.1.3
Analog device is connected to FXS port in Cisco 2821 H.323 gateway 12.4(11)XW Advanced IP services, to Call Manager 6.13. When the Analog device sends/performs a hookflash transfer by sending <hookflash signal> <pause> <dialed digits of 1460> to FXS port we hear some clicks then dialed digits and then the call disconnects. Please see configuration below:
dial-peer voice 118 voip
destination-pattern 1460 (Destination DN that I want FXS attached phone to hook flash to)
We know that we can get the hookflash transfer to work with MGCP, but we are wondering if Cisco has achieved this functionality in newer vesions of IOS for h.323. We opened a TAC and here is what TAC said:
I hope you are doing well.
Unfortunately, H.323 gateways do not support call transfer from hookflash of FXS ports. However, there may be a work around for your requested feature. You'll need an application script to control it.Please contact your Cisco Account Manager or Sales Engineer for this workaround since it is not troubleshooted by Cisco TAC."
Does anyone know if:
1.Cisco IOS and Call Manager support hookflash transfers made from analog devices attached to an FXS port on an H.323 voice gateway? If so, what are the commands to configure the router to complete the hookflash transfer and what is the correct version of Cisco IOS that we need to be running that supports this function?
2. Is there is an application script to do this in H.323?
3. Are we stuck with configuring MGCP to achieve this?
Re: Hookflash transfer support from FXS port on H.323 gateway?
Thanks for your reply. Update. Cisco TAC has come back and is now saying that there is a TAC support method to do this on H.323 with a TCL script which may do the blind transfer but fingers are crossed. Just wanted to get some certainty that MGCP Hybrid was still the way to go on achieving this.
Re: Hookflash transfer support from FXS port on H.323 gateway?
Yes I got it to work. I have attached the zip app-h450-transfer.188.8.131.52.zip that I got from TAC and instructions. It has a readme in it as well. Also here are the snippets from my router configuration. Hope this helps. Tonyc

From what I understand, you need assistance configuring hook flash transfer on an FXS port for an H.323 gateway. Please clarify if this is incorrect. Can you also tell me what the business impact is of this issue to your organization?
To do this you will need to download a TCL script to your router. The script can be found at:
You will need to copy the files from this zip file onto the router and then add configuration to have the calls invoke the script on the inbound H.323 dial-peer which will terminate to the FXS port. Here is an example:
service IVR_TRANSFER flash:app-h450-transfer.18.104.22.168.tcl
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
