as Daniel already told, the URI parameter should not contain non escaped double quotes:
https://www.ietf.org/rfc/rfc3261.txt

URI parameters: Parameters affecting a request constructed from
the URI.

     URI parameters are added after the hostport component and are
     separated by semi-colons.

     URI parameters take the form:

        parameter-name "=" parameter-value

     Even though an arbitrary number of URI parameters may be
     included in a URI, any given parameter-name MUST NOT appear
     more than once.

The angle-bracket "<" and ">" and double-quote (") characters are
excluded because they are often used as the delimiters around URI in
text documents and protocol fields. The character "#" is excluded
because it is used to delimit a URI from a fragment identifier in URI
references (Section 4). The percent character "%" is excluded because
it is used for the encoding of escaped characters.

delims = "<" | ">" | "#" | "%" | <">

ask your vendor to fix it or make a workaround in the captagent/sipcapture module
