> Easily reproducable.  Send any message to asterisk with "From: tel:+1000" in the headers.
> The crash is in pjsip_message_ip_updater.c:sanitize_tdata.   When we respond with even a 401, that function is called but it assumes that the From, To, and Contact uris are sip uris and casts the header's URI to {{pjsip_sip_uri *uri}}.  It then tries to call pjsip_param_find on {{uri->other_param}}.   Since the uri is actually a tel uri and {{other_param}} isn't at the same offset in {{pjsip_sip_uri}} as it is in {{pjsip_tel_uri}}, we get a crash.
