Hi Shridhar,
How to test STUN Keep alive Technique for Connection-less transport (UDP) by
sending STUN Binding requests from UE. Can you send me the sample SIP message?
All:
Please let me know who is familiar with GRUU. Please help me to understand the
GRUU mechanism.
Thanks & Regards,

Thanks Shridhar,
1) I have been added the line [authentication Digest] in the second REGISTER
message. SIPP will attach qop=auth_int, auth along with the second REGISTER.
It causes the issue. So we made code changes in auth.c and sending qop=auth
only, now it is getting 200 OK. It means IMS server is not accepting the qop
field containing two values. Can you clarify whether this is a bug in SIPP?
2) I am checking whether gruu (Globally Routable UA URI) is supporting. I have
been added the line Supported: gruu in the second REGISTER message and I am not
getting public id and temp id in the 200 OK contact header. Do I need to update
Open IMS server to the latest version? Can you help me in this?
Regards,
Praveen Raj Swaminathan

Hi Praveen,
That may be because your authorization credentials may not be satisfying the
server requirement.
Try sending the authorization credentials you are getting in 401. You can do
that by adding the following line in your second REGISTER message you will be
sending after receiving 401.
[authentication Digest]
Also, I am not sure if you are saying firewall as NAT or something else with
some access list.
But NAT has nothing to do with SIP unless it is an application level
gateway(ALG) also. Normally if you have a simple NAT in between your IMS and
SIPp, and is not able to open a pin hole, you will not receive 401 also.
Also please check if your IMS is using any authentication server like Radius or
Diameter and it has configured with appropriate user name and password.
Thanks & Regards,
Shridhar.

Hi,
I am using SIPp and Open IMS, both are running in linux machine. SIPp client is
not receiving 200 OK for registration message, keep on getting 401 message,
authorization info attached in REGISTER message. I hope some firewall will be
running in SIPp machine. May I know how to disable it for SIPp specific.
Thanks in advance.
