Pjsip is a SIP stack implementation implementing RFC3261 et al. whereas Google Hangout and Facebook are applications that are using an XMPP stack implementing RFC6120 et al. SIP does not interconnect with XMPP, they are different protocols. Please note that there is a difference between a protocol stack and an application using a protocol stack. Bria is a softphone application that is using both a SIP stack and an XMPP stack, that is why you can use it for both VoIP and messaging. But there is nothing preventing you from writing your own application that is using both pjsip and an XMPP stack for both VoIP and messaging functionality.
