Cisco SIP Phone 9971 with CME 8.8 Registration problem

Hi,

I'm trying to register 9971 with CME on ISR 2921.

All configurations was done in accordance with piece of config, presented in phone manuals.

On CME:

1    2037.0617.D891  172.4.4.3       1  1   103                  REGISTERED

But on the Phone it's still display "Phone is not registered"

In status messages there is dome messages about no tls file founded  and no vpn configured.

Everything seems configured properly but it still doesn't work.

ccsip messages show something strange:

Many messages like:

Received:

REGISTER sip:172.4.4.1 SIP/2.0

Sent:

SIP/2.0 200 OK

and after 3-5 times of OK it starts to send

Received:

REGISTER sip:172.4.4.1 SIP/2.0

Sent:

SIP/2.0 100 Trying

Sent:

SIP/2.0 500 Internal Server Error

IOS ver is15.2(1)GC

FIrmware is 9-2-3-27

What could it be?

Oh,  I figured that this happens because of conflict with sip-ua settings for external sip-proxy. Without this options all is ok.  We were going to refuse sip-ua anyway, so now we are just know that this kind of problem could happen
