From the original issue report opened by Nick Lewis: Many sip headers in many sip methods contain the ABNF structure name-andor-addr = name-addr / addr-spec Examples include the to-header, from-header, contact-header, replyto-header At the moment chan_sip.c makes various different attempts to parse this name-andor-addr structure for each header type and for each sip method with sometimes limited degrees of success. I recommend that this name-andor-addr structure be parsed by a dedicated function and that it be used irrespective of the specific method or header that contains the name-andor-addr structure Nick has also included unit tests for verifying these routines as well, so...heck yeah.
