>> gcc uastest.c -o uastest -L/opt/sip/target/lib/ -I/opt/sip/target/include/ -leXosip2

問題及其解決：

編譯問題：

uastest.c: In function `main':uastest.c:118: incompatible type for argument 1 of `osip_list_eol'uastest.c:122: incompatible type for argument 1 of `osip_list_get'

解決方法：

The osip_list_* interface has been changed in latest versions of

osip and osip_list_t in structures are not pointer any more.I think Updating is just a matter of adding"&"in front of remote_sdp->m_medias and to other list accessed.

運行問題：

[root@localhost linphonenew]# ./uastest./uastest: error while loading shared libraries: libosipparser2.so.4: cannot open shared object file: No such file or directory

解決方法：

#libosipparser2相關庫文件復制到usr、lib目錄下面

cp /opt/sip/target/lib/libosipp* /usr/lib

3/ 單機測試指導

本機ip：192.168.3.168

uac修改：

line23-26改為：

char *identity="sip:140@192.168.3.168"; //UAC1，端口是5060 char *registar="sip:133@192.168.3.168:5061"; //UAS,端口是5061 char *source_call="sip:140@192.168.3.168"; char *dest_call="sip:133@192.168.3.168:5061";

uas修改：

line44改為： i = eXosip_listen_addr (IPPROTO_UDP, NULL, 5061, AF_INET, 0);

4/ 呼叫彩E

本機ip：192.168.3.168

彩E：192.168.3.167

line80到85改為：

line26：

char *dest_call="sip:111@192.168.3.167:5060";

注意：111的用戶名不能就是該彩E的賬號，不能隨便換成其他的121之類，否則得到busy之類的應答信息。
