Unfortunately it doesn't work. if ((uri=~"^(sip:)?00(871-874|881|246)[0-9]*@([a-z]+\.)?mydomain\.com") || (uri=~"^(sip:)?00(871-874|881|246)[0-9]*@10\.0\.2\.200")) { if (isflagset(8)) {xlog("L_INFO", "Call to those locations are not allowed\n");}; sl_send_reply("404", "Not Found"); break; } else if ((uri=~"^(sip:)?00[0-9]*@([a-z]+\.)?mydomain\.com") || (uri=~"^(sip:)?00[0-9]*@10\.0\.2\.200")) { if (isflagset(8)) {xlog("L_INFO", "Call to anywhere in the World\n");}; # Strip first to digits (00) strip(2); # Prefix with 12345# prefix("12345#"); rewritehostport("123.123.123.123:5060"); # Remove credentials consume_credentials(); # Route call t_relay_to_udp("123.123.123.123", "5060"); break; } } else { ..... ..... ..... ..... can anyone tell my error here? thank you in advance regards, nhadie
