<div dir="ltr">I think this response is borderline. RFC3261 specifically mandates SINGLE character to be used, however the reason phrase might contain as many spaces as needed, so that it can be argued that in this particular case the reason phrase is " OK" versus "OK" normally.<div><br></div><div><pre class="gmail-newpage" style="margin-top:0px;margin-bottom:0px;break-before:page">---</pre><pre class="gmail-newpage" style="margin-top:0px;margin-bottom:0px;break-before:page"></pre><pre class="gmail-newpage" style="font-size:13.3333px;margin-top:0px;margin-bottom:0px;break-before:page"><span style="color:rgb(0,0,0)"><span class="gmail-h3" style="display:inline;font-size:1em;font-weight:bold"><h3 style="display:inline;font-size:1em"><a class="gmail-selflink" name="section-7.2" href="https://tools.ietf.org/html/rfc3261#section-7.2" style="color:black;text-decoration-line:none">7.2</a> Responses</h3></span>
SIP responses are distinguished from requests by having a Status-Line
as their start-line. A Status-Line consists of the protocol version
followed by a numeric Status-Code and its associated textual phrase,
with each element separated by a </span><font color="#ff0000">single</font><font color="#000000"> SP character.
No CR or LF is allowed except in the final CRLF sequence.

<p>To me 200 OK is perfectly valid. The operator should fix this
at his side. <br>

<div dir="ltr">Hello friends!<br>
<div>we have final equipment that does not meet 200OK
correctly. it adds an extra space between 200 and OK. from the
point of view of rfc is not very scary. but there is an
operator that cannot handle the given 200OK. I tried to fix it
with <span style="background-color:rgb(254,254,238);color:rgb(0,0,0)">change_reply_status
in module </span>sipmsgops.<br>
</div>
<div>but it rewrites the status-line with the same extra space. <br>
</div>
<div>Is this a bug?<br>
