Hello All,
I think I must be doing something wrong when attempting to create/register
multiple UAs. I am trying to register multiple UAs, but only the first UA
registers successfully. According to my Ethereal trace, the second UA does
not send the REGISTER message. It appears to me that the su_root_run()
might not be handling (or aware of the second UA)?
Here is the sequence of calls to the sofia-sip APIs:
1. su_init();
2. su_home_init(appl->home);
3. appl->root = su_create_root(NULL);
4. su_root_threading(appl->root, 0);
5. appl->nua[mk] = nua_create(appl->root,
ce_SipEventCb,
(nua_magic_t *)&mkData[mk],
NUTAG_URL("sip:192.168.72.191:5061"),
TAG_END());
6. handle = nua_handle(appl->nua[mk],
(nua_magic_t *)&mkData[mk],
NUTAG_URL("sip:[EMAIL PROTECTED]:5060"),
TAG_END());
7. nua_register(handle, TAG_NULL());
8. Here I fork a new process that calls su_root_run(appl->root) in an
infinite while loop.
9. su_root_threading(appl->root, 0);
10. appl->nua[mk] = nua_create(appl->root,
ce_SipEventCb,
(nua_magic_t *)&mkData[mk],
NUTAG_URL("sip:192.168.72.191:5062"),
TAG_END());
11. handle = nua_handle(appl->nua[mk],
(nua_magic_t *)&mkData[mk],
NUTAG_URL("sip:[EMAIL PROTECTED]:5060"),
TAG_END());
12. nua_register(handle, TAG_NULL());
The first UA is reflected in steps 4 - 7, above. The second UA is reflected
in steps 9 - 12, above.
Below are the DEBUG logs from the sofia SIP stack for the second UA only:
