[asterisk-bugs] [JIRA] (ASTERISK-26741) PJSIP device state exchange does not work between Asterisk instances on different network subnets

Jason Shrack commented on ASTERISK-26741:
-----------------------------------------

1. Configure 'Asterisk 1' and 'Asterisk 2' for devicestate publish per https://wiki.asterisk.org/wiki/display/AST/Exchanging+Device+and+Mailbox+State+Using+PJSIP. Relevant pjsip.conf configuration is attached.

2. I should expect to see 'asterisk-devicestate' PUBLISH events in the pjsip debug log output (attached) per https://wiki.asterisk.org/wiki/display/AST/Exchanging+Device+and+Mailbox+State+Using+PJSIP. 

3. No 'asterisk-devicestate' events occur when the devicestate publish server_uri target is set to the target IP address of the peer Asterisk instance that resides on a different subnet than the originating Asterisk instance. If you change the 'server_uri' target in pjsip.conf to a target IP address on the SAME subnet as the originating Asterisk instance you then see 'asterisk-devicestate' PUBLISH events in the pjsip debug output (attached). When you revert the configuration to the desired configuration (Asterisk peer target on a different subnet) no 'asterisk-devicestate' PUBLISH events are generated.

Let me know if you need additional supporting information.

> When configuring (per https://wiki.asterisk.org/wiki/display/AST/Exchanging+Device+and+Mailbox+State+Using+PJSIP) two Asterisk instances on different subnets to exchange device state information no PUBLISH events are generated. If you modify the server_uri attribute in pjsip.conf to a endpoint address on the same network as the source server PUBLISH event-devicestate are then generated. If you revert to a server_uri endpoint on a different network they are no longer generated and device state data is never received on the remote Asterisk server.
