pjsua2 example in python crash when run test code and register callback is executed
Hi
I'm following pjsua2 book documentation to create a SIP client using
python3.6 (from here: https://www.pjsip.org/docs/book-latest/html/index.html
)
I compiled myself pjsip 2.9 (tried too 2.8 and current code) but I cannot
run the code properly.
The test.py code is:
test.py
--------------------------------------------------------------------------------
import time
import pjsua2 as pj
uri = "sip:test@pjsip.org"
reguri = "sip:pjsip.org"
name = "test"
passwd = "pwtest"
uri = "sip:client1@localhost"
reguri = "sip:localhost"
name = "client1"
passwd = "1234"
port = 5061
Subclass to extend the Account and get notifications etc.
class Account(pj.Account):
def onRegState(self, prm):
print("***OnRegState: " + prm.reason)
pjsua2 test function
def pjsua2_test():
Create and initialize the library
ep_cfg = pj.EpConfig()
ep = pj.Endpoint()
ep.libCreate()
ep.libInit(ep_cfg)
Create SIP transport. Error handling sample is shown
sipTpConfig = pj.TransportConfig()
sipTpConfig.port = port
ep.transportCreate(pj.PJSIP_TRANSPORT_UDP, sipTpConfig)
Start the library
ep.libStart()
acfg = pj.AccountConfig()
acfg.idUri = uri
acfg.regConfig.registrarUri = reguri
cred = pj.AuthCredInfo("digest", "*", name, 0, passwd)
acfg.sipConfig.authCreds.append( cred )
Create the account
acc = Account()
acc.create(acfg)
Here we don't have anything else to do..
time.sleep(10)
Destroy the library
ep.libDestroy()
main()
if name == "main":
pjsua2_test()

--------------------------------------------------------------------------------
It seems it is failing when parsing the registration callback, but in my
code it seems it all ok. The code fail too with invalid credential and only
if asterisk server is running, if not is running, register callback (this
log line no appear: 16:21:22.019 pjsua_acc.c
....sip:client1@localhost: registration success, status=200 (OK), will
re-register in 300 seconds) and it does not crash.
The problem happens at C level. The asterisk server is registering properly
the user:
asterisk.log
----------------------------------------------------------------
Asterisk Ready.
*CLI> -- Registered SIP 'client1' at 127.0.0.1:5061
--------------------------------------------------------------------------------
How can I solve this?
Thanks.
