If I provide the URI "sip:alice@server_pjsip:25060", Bad Things will happen. The colon you added to the strstr call narrows the scope of the problem a little, but it still exists.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">That scenario will never occur. That particular example would call into the message tech registered as 'sip' (currently handled by chan_sip). res_pjsip_messaging's message tech is registered as 'pjsip', so any messages that need to be routed to res_pjsip_messaging have to be prefixed as following: pjsip:alice@server_pjsip:25060. So the code should always copy correctly.
Any malformed uri before/beyond that will not be parsed correctly by the pjsip library, so the 'to' will end up being invalid and the message won't be sent.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I thought that since the "sip:" scheme scenario was partially handled that it was actually possible. Given that it is not actually possible, this function can be simplified to:
ast_assert(!strncmp(uri, "pjsip", 5));
return ast_strdup(uri + 2);</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">pjsip's message technology was being registered as 'sip', which was causing it to not load due it conflicting with chan_sip's registered 'sip' technology for messaging. It now registers as 'pjsip'. However, due to this change the "to" field for outgoing pjsip messages need to be prefixed with 'pjsip:' instead of 'sip:'. Incoming messages to res_pjsip_messaging will automatically have their "to" fields altered in order to accommodate the change. Outgoing messages also handle changing it back to 'sip' before being sent so the pjsip library will properly handle it.</pre>
