Hi,
Please help! I am trying to forward calls to PSTN gateway. But I run the
ser code below, the call went through for the PSTN gateway but I can see
multiple request of ACK. Anyone know what is happening ...thanks.!! Please
HELP.
<<ser.txt>> <<error.txt>>

I guess the problem is in this:
if (method=="ACK"){
sl_send_reply("", "ACK");
break;
};
What is this supposed to do ? You must not send any replies to ACK.
