When two Jabber clients (XMPP) are connected, only one can receive messages, both can send

I have a Windows XMPP client - PSI and android one - IMO. I am connected to the same custom server using two different resources (the host name on the desktop, I don’t know what IMO uses as a resource). When someone sends me a message, only the desktop can receive it. Android client can send only.

What needs to be configured for clients to be able to simultaneously receive messages on both clients?

Figured it out. XMPP has priority assigned to resources. See 11.1 at http://xmpp.org/rfcs/rfc3921.html#rules . Valid Range: -127 .. +128

IMO sends priority 1 (at least in my version). By setting the priority in the PSI to -120, my phone client always received a message. I will play with priorities to take advantage of the automatic shutdown feature, which lowers priority.

If you have administrator rights on the Openfire server, setting the system property "route.all-resources" to "true" should allow all connected clients to receive a message sent to Jabber ID. This worked in my case.
