[Serusers] t_replicate can't call to registered endpoint<BR><BR>> Dear
all<BR>> <BR>> We have setup two SER servers which replicates endpoint
registration<BR>> info to the second server as follow: <BR>> <BR>>
Server
A:<BR>>
if (method=="REGISTER") {<BR>>
<BR>>
#if (src_ip=="xxx.xxx.xxx.xxx")
{<BR>>
#
save("location");<BR>>
#
break;<BR>>
#};<BR>>
<BR>>
if (!www_authorize("", "subscriber"))
{<BR>>
www_challenge("",
"1");<BR>>
break;<BR>>
};<BR>>
<BR>>
if (!src_ip==xxx.xxx.xxx.xxx)
{<BR>>
t_replicate("xxx.xxx.xxx.xxx",<BR>> "5060");
<BR>>
};<BR>>
<BR>>
save("location");<BR>>
break;<BR>>
};<BR>> <BR>> Server B:<BR>>
<BR>>
save_noreply("location");<BR>> <BR>> <BR>> registration process went
fine. But when we use Server B to call the<BR>> replicated endpoint,
endpoint does not response to the INVITE<BR>> message. Port and IP both
are correct in the INVITE message. <BR>> <BR>> What could be the
problem?<BR>> <BR>> Regards<BR>> <BR>> <BR>> <BR>> <BR>>
