Description:I use pjsip for sip phone registration, asterisk restart randomly(about 10 times per day), since I have another server use pjsip to register to a SIP provide and no problem, I think it's something to do with registrar part. I tried centos 6.7, centos 7 and ubuntu 14, it's same, sometimes it's segmentation fault, sometimes it's bla bla magic number...

phone: yealink, grand stream

tried several asterisk 13, all same, tried clone from asterisk pjsip or download pjsip2.4.5 , same
