Rats.
Where does the crash occur? Is it in Asterisk's lower-level res_pjsip code, or is it in PJSIP itself? If the crash is in Asterisk, it sounds like there are some assumptions being made in the lower levels that shouldn't be made and those should be fixed there. If the crash is in PJSIP (especially if it's an assertion failure), then that means we do have to do some validation before calling down into PJSIP, but that validation should be left to the core res_pjsip code rather than being the duty of users of the res_pjsip API. If we do need to perform validation of the URI, the implementation has some issues. It's limiting since it only allows for sip: URIs and not, for instance, sips: URIs. It also only checks that the prefix is valid for a sip: URI. It does no other checking of the rest of the URI. A more thorough way of checking validity of the URI is to use pjsip_parse_uri() from PJSIP. If you then want to make sure that the URI is a sip: or sips: URI, you can use the PJSIP_URI_SCHEME_IS_SIP() and PJSIP_URI_SCHEME_IS_SIPS() macros to do so. - Mark ----------------------------------------------------------- This is an automatically generated e-mail.
