Cannot Register on Asterisk-16.12.0

Greetings All,

I have Asterisk-16.12.0 running on VMWare. I copied PJSIP config line for line and my Bria softphone will not register. After it times out, the error message says " no route to host ".

Is there an ACL needed for PJSIP? I am new to asterisk/linux. Do i need to open something up in Centos 8,2?

I can ping the Asterisk machine from any other machine and my smart phone. What happened to sip set debug command in 16.12.0? Is it pjsip set logger?

Thank you,


Also, 'tcpdump' will show incoming packets before 'iptables' so it may yield another clue.

It died with chan_sip.

My fingers have a long memory, so I added these aliases:

	pjsip set debug off		= pjsip set logger off
	pjsip set debug on		= pjsip set logger on
	sip set debug off		= pjsip set logger off
	sip set debug on		= pjsip set logger on


If I have both sip.conf and pjsip.conf on my machine, do I need to change anything or get rid of sip.conf?


chan_sip is deprecated and should not be used unless you really, really need it – but even then, you should ask for help. Maybe someone knows how to do it with PJSIP.


I still cannot get my Bria Softphone to connect to PJSIP. In WireShark I can see the the phone make a
696 Request Options sip:; then a 736 Request REGISTER sip:
(1 binding ).

There is no response from Asterisk. I am posting my PJSIP.conf file in short. Please have a look and tell me what I need to change. When I turn debug on nothing happens when I try to register.

Here’s the file:

Thank you,


I see the Asterisk Server sending ICMP packet at the Bria softphone and Wirehark saying in the info field " Destination unreachable( Communications administratively filtered ). IS there a command in Centos I need to issue?
