PJSUA2 - Example Pythons Script Unsolicited NOTIFY caused core dump

[slipalong]

Describe the bug

import pjsua2 as pj import time import threading

class Account(pj.Account): def onRegState(self, prm): print("***OnRegState: " + prm.reason)

def onMwiInfo(self, prm):
    print("OnMwiState: " + prm.reason)

def onBuddyState(self, prm):
    print("OnBuddyState: " + prm.reason)

def onIncommingSubscribe(self, prm):
    print("OnSubscribeState: " + prm.reason)

def initalise_sip_stack():

ep_cfg = pj.EpConfig()
ep = pj.Endpoint()
ep.libCreate()
ep.libInit(ep_cfg)

sipTpConfig = pj.TransportConfig()
sipTpConfig.port = 5060
ep.transportCreate(pj.PJSIP_TRANSPORT_UDP, sipTpConfig)
ep.libStart()

acfg = pj.AccountConfig()
acfg.idUri = "sip:[email protected]"
acfg.regConfig.registrarUri = "sip:192.168.1.10"
creds = pj.AuthCredInfo("digest", "ccmsipline", "iann", 0, "12345")
acfg.sipConfig.authCreds.append(creds)

acc = Account()
acc.create(acfg)

return ep

if name == "main":

ep = initalise_sip_stack()

time.sleep(100)

ep.libDestroy()

Steps to reproduce

Copy and paste the example python script in to main.py and run it with a valid account on a Cisco CUCM 12.5. After the sip registers the CUCM sends an up solicited NOTIFY to update VM MWI (I think). The code count seem to be able to fins the account in an internal list to map the Notify to one of the 3 accounts
