When I use the topology hiding module an extra header parameter named 'thinfo' is added to the contact field as explained in the docs. The field parameter value contains parenthesis surrounding it. For example the contact header I got was:</div><div><br></div><div>Contact: <sip:52.70.236.51:51842;transport=tcp;thinfo=<b>"</b>dm1KMyPQIyIU9fUQFpcQ0AVUdEXFwdbHNjClRbTF9TAGlwdkwWCBgeFFwoM3BMCBphbfKX18CEpfRENWAGhpfApUU0ddVANo<b>"</b>></div><div><br></div><div>The SUBSCRIBE request is being routed to another server which uses Java's Jane library. This library attempts to parse the headers of the SIP message and throws an exception of this contact header. When I remove the parenthesis it does work. My question is whether parenthesis are allowed in contact field headers or not. It seems that either opensips should not add these or that Jane has a bug in I tried to look in the <a href="https://tools.ietf.org/html/rfc3261#section-20.10" target="_blank">RFC-3261 section 20.10</a> but didn't get a concrete answer.</div><div><br></div><div>Here are the Java Jain implementation of trying to parse the header and receiving an exception, I also have a <a href="https://drive.google.com/open?id=0B1qvsk1sLQdPb2MzZkNVQXFncGM">sample</a> of this project in case it helps:</div><div><br></div><div><pre style="font-family:Menlo;font-size:9pt">String sWithParenthesis = <span style="color:rgb(0,128,0);font-weight:bold">"Contact: <sip:52.70.236.51:51842;transport=tcp;thinfo=</span><span style="color:rgb(0,0,128);font-weight:bold">\"</span><span style="color:rgb(0,128,0);font-weight:bold">dm1KMyPQIyIU9fUQFpcQ0AVUdEXFwdbHNjClRbTF9TAGlwdkwWCBgeFFwoM3BMCBphbfKX18CEpfRENWAGhpfApUU0ddVANo</span><span style="color:rgb(0,0,128);font-weight:bold">\"</span><span style="color:rgb(0,128,0);font-weight:bold">>" </span>+ <span style="color:rgb(0,128,0);font-weight:bold">"</span><span style="color:rgb(0,0,128);font-weight:bold">\n</span><span style="color:rgb(0,128,0);font-weight:bold">"</span>;</pre></div><div> <span style="font-family:Menlo;font-size:9pt">HeaderParser h = ParserFactory.</span><span style="font-family:Menlo;font-size:9pt;font-style:italic">createParser</span><span style="font-family:Menlo;font-size:9pt">(sWithParenthesis);</span></div><pre style="font-family:Menlo;font-size:9pt">SIPHeader header = h.parse();<br>System.<span style="color:rgb(102,14,122);font-weight:bold;font-style:italic">out</span>.println(header.getName());<br>System.<span style="color:rgb(102,14,122);font-weight:bold;font-style:italic">out</span>.println(header.getHeaderValue());</pre><div><br></div><div>And this is the exception I am getting:</div><div><br></div><div><div><font color="#cc0000">Exception in thread "main" java.text.ParseException: [C@6477463f</font></div><div><font color="#cc0000">Expecting >>>><<< got >>>"<<<</font></div><div><font color="#cc0000"><span style="white-space:pre-wrap"> </span>at gov.nist.core.LexerCore.match(LexerCore.java:284)</font></div><div><font color="#cc0000"><span style="white-space:pre-wrap"> </span>at gov.nist.javax.sip.parser.AddressParser.nameAddr(AddressParser.java:63)</font></div><div><font color="#cc0000"><span style="white-space:pre-wrap"> </span>at gov.nist.javax.sip.parser.AddressParser.address(AddressParser.java:112)</font></div><div><font color="#cc0000"><span style="white-space:pre-wrap"> </span>at gov.nist.javax.sip.parser.AddressParametersParser.parse(AddressParametersParser.java:55)</font></div><div><font color="#cc0000"><span style="white-space:pre-wrap"> </span>at gov.nist.javax.sip.parser.ContactParser.parse(ContactParser.java:69)</font></div><div><font color="#cc0000"><span style="white-space:pre-wrap"> </span>at com.vonage.Main.main(Main.java:14)</font></div></div></div></div></div></div><div class="inbox-inbox-uyb8Gf" style="color:rgb(33,33,33);font-size:13px"><div><div title="Show quoted text" tabindex="0" class="inbox-inbox-mg" style="border-radius:2px;color:rgb(117,117,117);display:inline-block;padding:0px 2px">…</div></div></div><br><div class="gmail_quote"><div dir="ltr">On Tue, Sep 26, 2017 at 7:31 PM Răzvan Crainea <<a href="mailto:razvan@opensips.org">razvan@opensips.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<tt>Hi, Royee!<br>
<br>
There's no need for an actual dialog (from OpenSIPS pov) - you can
simply route the NOTIFY messages as sequentials - route them
according to the Record-Route headers.<br>
<br>
Best regards,<br>

<div dir="ltr">Hi,
<div><br>
</div>
<div>I am using opensips 2.1 as a SIP proxy and I am trying to
figure out how to best handle SUBSCRIBE messages which need to
be routed through to another SIP component. As I read in the <a href="https://tools.ietf.org/html/rfc3265#ref-1" target="_blank">rfc3265</a> an initial (out of call)
SUBSCRIBE creates a dialog which NOTIFYs and following
SUBSCRIBE messages are part of and are routed within the same
dialog. </div>
<div><br>
</div>
<div>From looking at the opensips code I see that when
"create_dialog" is called then the request is only handled if
it is an INVITE request. So I'm trying to understand what is
the proper way of handling the SUBSCRIBEs that come from the
devices and the NOTIFYs that come from the PBX after the
SUBSCRIBE is accepted.</div>
<div><br>
</div>
<div>If there are examples for handling such SUBSCRIBEs that
would be great.</div>
<div><br>
</div>
<div>Thanks,</div>
