EXOSIP_MESSAGE_NEW, /**< announce new incoming request. */

我也不是很明白，理解是： EXOSIP_CALL_MESSAGE_NEW是一个呼叫中的新的消息到来，比如ring trying都算，所以在接受到后必须判断

该消息类型，EXOSIP_MESSAGE_NEW而是表示不是呼叫内的消息到来。

该解释有不妥地方，仅供参考。

问题及其解决：

编译问题：

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’

解决方法：

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.

运行问题：

[root@localhost linphonenew]# ./uastest

./uastest: error while loading shared libraries: libosipparser2.so.4: cannot open shared object file: No such file or directory

解决方法：

#libosipparser2相关库文件复制到usr、lib目录下面

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

3/ 单机测试指导

本机ip：192.168.3.168

uac修改：

line23-26改为：

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

4/ 呼叫彩E

本机ip：192.168.3.168

彩E：192.168.3.167

line80到85改为：

snprintf (tmp, 4096,

“v=0/r/n”

“o=- 6 2 IN IP4 192.168.3.46/r/n”

“s=CounterPath X-Lite 3.0/r/n”

“a=rtpmap:107 BV32/16000/r/n”

“a=rtpmap:101 telephone-event/8000/r/n”

“a=sendrecv/r/n”);

line26：

char *dest_call=”sip:111@192.168.3.167:5060″;

注意：111的用户名不能就是该彩E的账号，不能随便换成其他的121之类，否则得到busy之类的应答信息。
