[cisco-voip] vg224 hookflash transfer

[polo person]

I had a similar problem on an analogue extension connected to a VG224 where the extension could not put calls on hold or transfer them.  The VG224 and the IVR system need to be configured for the correct Hook Flash duration.  i.e. if the IVR is sending a hook flash which is too long, the VG224 will see this as the IVR hanging up.  The standard Hook Flash time should be around 100ms.  I set our VG224 to have a hook flash time of 80ms min and 100ms max and this worked perfectly with the analogue extension.

 

If you set both your VG224 and your IVR to these values (the IVR may already be set correctly of course) it should work.

 

Cheers

 

Simon

I had everything correct, however, I made a stupid mistake - I had my max calls on the port set to 1 – that was causing the hangup. I fixed that and now I no longer get disconnected but it never completes the transfer. >From all of the documentation I’ve read it appears that the SCCP port requires a “#2” transfer code after the 2nd hookflash. The IVR appears to just hang up while the cisco port just sits there and waits for the interdigit timeout and then re-rings the port which opens the IVR connection back up and you start at the opening IVR greeting all over again. To reprogram the IVR system to add a “#2” is going to take an act of congress.
 
Not sure what I can do.

i believe you need to enable a feature mode in order to get hookflash since it is considered a supplementary feature.

We recently integrated a very old IVR system (that was previously integrated into an Avaya) into a UCM 6 system via 8 ports on a VG224. When you call the system and press 0 for an operator it attempts to transfer you to an extension on the Cisco system. The system does this by sending a hookflash, then 4 digits, and then a 2nd hookflash. When testing you hear the digits but then the call is disconnected. In debugging the vg224 we see this exact event transpire (hookflash, digits, hookflash), however, the Callmanager system does not interpret/handle the hookflash transfer properly. We have tried configuring the ports as both MGCP and SCCP, neither with any success.
 
Is there some parameter, etc., that I am missing?
 
As always your time is appreciated.
 
Thanks,
