Maybe it is time to look at ZTE traces/logs.
P.S.
Try to check in docs meaning of X-ZTE-Cause

Hi, I knew, But i have not access to ZTE's pcscf.
Thank you.
But what about my question?Why the UE could not register via SEMS?

Hello,
It's not directly related to your question but keep in mind that SBC
should be put after vendor's/ZTE p-cscf if possible. Otherwise you
will
have QoS issues (if Rx is enabled/used) because of rewritten SDP from
SBC/B2BUA.

Ivo

Hello,
I am working with IMS (ZTE vendor), I want to use SBC in front
of IMS
network for some security policy (Hide
Topology),
I used SEMS as SBC in this regards, (like what we have in
IMS/SEMS in
kamailio by Mr Carsten Bock).
When the Sebscriber want to register, The Register request
received by
sems and the forward to IMS(ZTE), But the
"503 Service
Unavailable" is
received from IMS.
I enable "enable_reg_caching=yes" in register.sbcprofile''s
configuration file in sems.
If i use kamailio, instead of SEMS, The Registration request is done
successfully.In Kamailio i just forward the Register request to
IMS.like this:
route {
if (is_method("REGISTER")) {
$du = "sip:172.23.1.1:5080
<http://172.23.1.1:5080>";
route(RELAY);
}
}
Let me know do the issue is from myself or from IMS(ZTE)?
In the fillowing, I paste all SIP Register signalling. First in
kamailio, second with SEMS.
