Hi everyone. I want to use an extension for an FCT. I want to call vodafone numbers over the vodafone gsm and others over the other gsm network. I can select it on the prefixes. However, my FCT can only choose one network from the other by selecting the rank of the network (by dialing 1 for the first gsm, in this case vodafone, by selecting 2 for the other network) and then pressing the flash. So I have to send to the FCT a flash. But I don't know how to send it. I have two different options. I can let asterisk decide when I choose prefix 054 to take the 1st line on the fct and then send flash. Or I can let my audiocodes to manipulate when I dial the prefix 054 and then send a flash. Which one should I pick. And at all HOW can I send a flash. What is the code of flash? Thanks.
