[Linphone-developers] Help: Problem with sip registration using IPv6

[akkawi]

i am trying to use the osipua  for my application for IPv6. when i set 
IPv4 for the outbound proxy it works fine. But if set it for IPv6, the 
osipdialog doesn't copy the address, and the address is empty.  This 
happen  in the osipdialog in the function "osip_dialog_send_request 
(OsipDialog * call_leg, sip_t * sipmsg)". The function 
ua_transaction_get_destination (transaction, &dest, &port) called int 
the function osip_dialog_send_request  returns dest as null pointer.   
What is the porblem?

Other problem: The current osipua tries to resolve the ip address of the 
registerar. In case that  hostname of the registrar in not reachable 
from the client side for example by hiding it using the outbound proxy, 
it return an error. How can i fixed this?

see follow:
   osipua_init();
   ua=osip_ua_new();
   
osip_ua_set_contact(ua,"sip:[2008:638:201:8000:20c:6eff:fe20:7978]:5090");
   
osip_ua_set_outbound_proxy(ua,"2008:638:201:8000:20c:6eff:fe20:7978","xxxxxx");
   call=osip_dialog_new(ua);
   regctx=registration_ctxt_new();   
   
registration_ctxt_set_registrar(regctx,"sip:[2008:638:201:8000:20c:6eff:fe20:7978]:6070");//[2008:638:201:8000:20c:6eff:fe20:7978]:5090");
   registration_ctxt_set_password(regctx, "mypassword");
   registration_ctxt_set_address_of_record(regctx, "sip:address@hidden");
   registration_ctxt_set_expires(regctx,60000);
   osip_dialog_register(call,regctx);
