I have a vg224 voice gateway running a version of 12.4 with 24 voice ports. I'm having issues getting feature access codes to work. Specifically, a user wants to forward a fax (when it runs out of toner) to another fax line using the procedure outlined in the document for accessing that feature. There are other users who wish to setup a three-way conference from a Polycomm using the hookflash. This doesn't work as well. I believe that the vg224 is detecting the hookflash because when I change the timing settings on the voice port (for instance, increase it from the default of 1000 ms to 1550 ms) there's a difference in how long the phone has to be onhook before a disconnect. However, when the hookflash is activated, nothing happens. It's either ignored by the system or the line disconnects. I asked one of my in-house techs about this and he claimed that these features wouldn't work with FXS ports and would require DID ports instead? Does that sound right?
