FXO hold trunk

You have a problem for CO hold trunk. When caller call from outside to CUE via CO incoming trunk (FXO) and termiate to AA, caller will enter extn for call transfer. We find that if caller hangup, FXO (CO incoming trunk) still holding and cannot release until reset FXO port in vg. Is there any parameter set in vg to prevent CO hold trunk?

This is what you are experiencing:

In addition to what the document asys note:

- The most effective way to eliminate that, and get all the advantages of a digital connection, is using ISDN BRI instead of FXO.

- Unless you are in north america, "groud start" will not be available to to you. The only method independent from telco, is "tone detection disconnect".
