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

 

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:[email protected]";   //UAC1，端口是5060
    char *registar="sip:[email protected]:5061"; //UAS,端口是5061
   char *source_call="sip:[email protected]";
   char *dest_call="sip:[email protected]: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" "c=IN IP4 192.168.3.46/r/n" "t=0 0/r/n" "m=audio 52386 RTP/AVP 107 0 8 101/r/n" "a=alt:1 1 : 0+Y3WBhV SIknnQeS 192.168.3.46 52386/r/n" "a=fmtp:101 0-15/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:[email protected]:5060";
