The secondary dialtone is usually provided by the serving switch, which is this case would be the PABX. How is the PABX routing the call? Usually, the PABX will collect all the digits before sending the call out a trunk. If that's the case, the PABX is still holding the call when the caller should be hearing the secondary dialtone.

Dial tone will be provided with CUCM or CME or UC500

or by going offhook if u dont have 3 above GW cannot provide dialtone by entering a digit
