> I'm trying to exchange device states between two asterisk boxes (both on 13.6.0) connected via an openvpn tunnel. Tunnel and routing are fine.
> First box is 192.168.1.1 (instance-hannover) and second box is 192.168.2.1 (instance-bremen)
> Both systems are using pjsip 2.4.5.
> The setup is like the description in the wiki: https://wiki.asterisk.org/wiki/display/AST/Exchanging+Device+and+Mailbox+State+Using+PJSIP
> The setup on 192.168.1.1 (instance-hannover) is:
> {code}
> [transport-udp]
> type=transport
> protocol=udp
> bind=0.0.0.0
> local_net=192.168.0.0/16
> local_net=127.0.0.1/32
> [instance-bremen]
> type=endpoint
> transport=transport-udp
> [instance-bremen-devicestate]
> type=outbound-publish
> server_uri=sip:instance-hannover at 192.168.2.1
> event=asterisk-devicestate
> [instance-bremen]
> type=inbound-publication
> event_asterisk-devicestate=instance-bremen
> [instance-bremen]
> type=asterisk-publication
> devicestate_publish=instance-bremen-devicestate
> device_state=yes
> {code}
> And the counter part on 192.168.2.1 (instance-bremen):
> {code}
> [transport-udp]
> type=transport
> protocol=udp

> type=inbound-publication
> event_asterisk-devicestate=instance-hannover
> [instance-hannover]
> type=asterisk-publication

> A SIP request is received from 192.168.2.1 outgoing port 1025.
> The response is sent back to 192.168.2.1:1025, but not received there, cause pjsip is listening on port 5060.
> This results in:
> {code}[2015-11-23 13:46:39] NOTICE[8727]: res_pjsip_outbound_publish.c:923 sip_outbound_publish_callback: No response received for outbound publish 'instance-hannover-devicestate'
> {code} on 192.168.2.1 and vice versa.
> I can't figure out, how to send the response back to 5060, settings like "from_uri" seem to be ignored.
> The wiki documentation is quite not very clear here.
> I don't post the full pjsip/extension config here, because I think it's not relevant and the problem is about pjsip publishing.
