    196196/** 
     197 * Perform Via sent-by checking as specified in RFC 3261 Section 18.1.2, 
     198 * which says that UAC MUST silently discard responses with Via sent-by 
     199 * containing values that the UAC doesn't recognize as its transport 
     200 * address. 
     201 * 
     202 * In PJSIP, this will cause response to be discarded and a message is 
     203 * written to the log, saying something like: 
     204 *  "Dropping response Response msg 200/INVITE/cseq=608594373 (rdata00A99EF4) 
     205 *   from 1.2.3.4:5060 because sent-by is mismatch" 
     206 * 
     207 * The default behavior is yes, but when the UA supports IP address change 
     208 * for the SIP transport, it will need to turn this checking off since 
     209 * when the transport address is changed between request is sent and  
     210 * response is received, the response will be discarded since its Via 
     211 * sent-by now contains address that is different than the transport 
     212 * address.
