2009/10/21 Elias Baixas &lt;elias.baixas(a)voztele.com&gt;om>: Hi Elias, a URI parameter cannot contain quotation (double quotation), neither in the key or in the value. This is: Valid: 1) From: <sip:elias@sipmola.org &lt;sip%3Aelias(a)sipmola.org&gt;;aaa=111&gt;;bbb=222 2) From: <sip:elias@sipmola.org &lt;sip%3Aelias(a)sipmola.org&gt; ;aaa=111>;bbb="222" Invalid: 3) From: sip:elias@sipmola.org &lt;sip%3Aelias(a)sipmola.org&gt;;aaa=&quot;111&quot;&gt; 4) From: sip:elias@sipmola.org &lt;sip%3Aelias(a)sipmola.org&gt;;&quot;aaa&quot;=111&gt; 5) From: <sip:elias@sipmola.org &lt;sip%3Aelias(a)sipmola.org&gt; ;aaa=111>;"bbb"=222 Note that in case 2) bbb is a header parameter key, so its value can be quoted. Case 5) is invalid since the header parameter key ("bbb") cannot be quoted. NOTE: I just mean *double* quotation ("). Using single quotation (') is allowed in key and value for SIP URI parameters and header parameters. The following is valid: 6) From: <sip:elias@sipmola.org &lt;sip%3Aelias(a)sipmola.org&gt; ;'aaa'='111'>;'bbb'='222' Regards. PS: If it's useful for you, I coded some time ago a SIP grammar tester (using Ragel) implementing *100% strictly* the SIP ABNF grammar, so I can check with it *any* SIP ABNF component: http://dev.sipdoc.net/projects/ragel-sip-parser/wiki/Phase1 -- Iñaki Baz Castillo &lt;ibc(a)aliax.net&gt;
