十万火急！SS7送主叫问题

局端机房说我送的主叫地址属性是国内的，必须改成本地地址属性，请问咋弄呀？现在所有电话都打不出去，非常着急，希望兄弟赶紧支个招，谢谢！

你这个可能要改代码，把IAM消息里面的主叫号码属性修改一下。具体怎么改你需要参考一下ss7的规范，规范可以从通信人博客下载到。

请问改哪个源程序，具体改哪儿，改动大吗，复不复杂，我对SS7一点不懂，还望多指教，谢谢！

Dear awa2008, your question is very common in China mainland. You should modify l4isup.c as blow :

/* Calling party's category Q.763 (3.11). */
param[0] = 0x0c; /* Ordinary calling subscriber for local */
//param[0] = 0x0a; /* Ordinary calling subscriber for distance*/
isup_msg_add_fixed(msg, sizeof(msg), ¤t, param, 1);

these code are in function isup_send_iam , just replace 0x0a with 0x0c .

After this , you need make a new chan_ss7.so and replace the old one.

希望一次成功，谢谢！
