[SR-Users] UAC module

[Ron Hopson]

Daniel,

Thank you for your response.  I was away the remainder of the past week.

Calls to uac_reg_lookup() and uac_reg_request_to(), with prior 
assignment or no assignment, yield "fixing failed (code=-1)".  For example,

      if(uac_reg_request_to("$rU", 0)){        #line 76

  0(16293) DEBUG: <core> [route.c:929]: fixing uac_reg_request_to()
  0(16293) ERROR: <core> [route.c:1216]: fixing failed (code=-1) at 
cfg:/usr/local/etc/kamailio/kamailio.cfg:76

I am most interested in function uac_reg_request_to().  I expect to 
receive a REGISTER command from a local user and forward it with proper 
credentials to a remote server.  I believe uac_reg_request_to() will 
read (a memory image of) the uacreg file for the remote user's name and 
credentials, and manage registration at the remote server.  Is this correct?

I would like to lookup the registration information by $tU. Both of the 
following code snippets get "fixing failed".
(1)     if(uac_reg_request_to("$tU", 0)){
and
(2)        $rU = $tU;
          if(uac_reg_request_to("$rU", 0)){

Thank you for any hints or examples of how to use uac_reg_request_to().

BTW:  How do I become a member of sr-users at lists.sip-router.org?

regards,
Ron Hopson
