> Fixed error with quoted parameters on URIs


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 at sipmola.org;aaa=111>;bbb=222
2) From: <sip:elias at sipmola.org;aaa=111>;bbb="222"

Invalid:
3) From: sip:elias at sipmola.org;aaa="111">
4) From: sip:elias at sipmola.org;"aaa"=111>
5) From: <sip:elias at sipmola.org;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 at sipmola.org;'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:
