We were using h323 3945's with vwic-t1's setup for fxs-loop-start trunks and when a caller pressed zero it would do a hookflash, the router would recognize it using the app-h450-transfer-2.0.0.9.tcl script, give it dialtone and it would auto dial to the operator.
Since installing the h323 4331's with nim-t1's using the same config and script the hookflash isn't recognized. Does anyone have any ideas to make the 4331 recognize the hookflash so it can get dialtone to reach the operator?
