| There are two trunks. One is CO and the other is voice ip trunk to branch in USA. In order to save cost, I want guys who come here to call the phone number of USA through internal Voice IP. But how can I connect two trunks? For example, I call the phone number of local company from hotel, and the next step I should do is dialing ACOD of Voice IP trunk to connect the phone in USA.Thanks a lot in advance. |
