<div dir="ltr">Hello Bogdan,<br><br><br>thanks a lot for your clear answer.<br><br>I am now comparing out the 2 different 200 OK responses: one from other sip-server works fine on Nokia SIP client, the other comes from Opensips not.<br>

<br>
It is a must (by RFC3261) to have a TO-tag in any final reply (including 200 OK) . What are you asking is a violation of the SIP RFC.<br>
<br>
I guess the problem is in the SIP client from the NOKIA device. You should try to solve it there.<br>
<br>
<br>
Anyhow, to answer to your question, no, there is no way to send a 200 OK without To-tag :).<br>
<br>
Regards,<br>
Bogdan<br>

Hello,<br>
<br>
<br>
I am using Opensips 1.4.2 as SIP-Server and a Nokia N95 as SIP-Client.<br>
<br>
But I got error -17701 on N95 by registering with 200 OK response from the server.<br>
<br>
I compared the 200 OK SIP-message with other worked SIP-Server und found out, that the problem maybe is on the To-Tag in the response.<br>
<br>
Now I want the Opensips not adding to-tag into the 200 OK response for register. Can anyone give me a help?<br>
<br>
<br>
Thanks<br>
<br>
Pai<br></div></div>
