Description

In RT#1205sysmocom got a trace that showed a message flow like the following resulting in a re-transmission by the Mobile Station

MS                                             BTS
    - SABM SAPI=0, Paging Response ---->   
    <- SABM SAPI=3 ---------------------
    <- SABM ACK (UA?) for SAPI=0    ----
    - SABM SAPI=0, Paging Response ---->
</prE>

We need to investigate if we should start sending messages with SAPI=0 first or if there are other priority requirements that we need to consider.
