<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I'm getting a segfault with the test "tel:911". userinfo == NULL causes strchr to segfault on Ubuntu x86_64 (eglibc 2.17). I believe we need to add:
userinfo = uri = "";
blank userinfo to prevent the segfault, blank uri to prevent "911" from being returned in residue.

<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;">Return userinfo when RFC 3966 does not include neither global number, nor context.
In this case hostport will not be available.
Avoid NULL string reference segmentation fault by adding explicit test && (userinfo != NULL) before strstr test.</pre>

See https://issues.asterisk.org/jira/browse/ASTERISK-17179 for a description of the original isssue.
I have been patching all versions since Asterisk 1.6. I would like to include the code into the main trunk for version 13.
Previously Asterisk was failing with error on incoming IMS call:
Nov 13 17:52:05 NOTICE[27459]: chan_sip.c:6973 check_user_full: From address missing 'sip:', using it anyway
Nov 13 17:52:05 WARNING[27459]: chan_sip.c:6525 get_destination: Huh? Not a SIP header (tel:0987654321;phone-context=+32987654321)?
Reason: tel: protocol was not recognized.</pre>
