---------------------------------------------------------------------- 
closing this as https://issues.asterisk.org/view.php?id=16909 fixes it.

Summary. If our Jtec ISDN switches reported a REJ I-frame, libpri goes
into retransmission, if 4 or more i-frames were sent from asterisk in quick
succession, the 1st sometimes got through.
The result was continuous retries of 4 or more i-frames, with the switch
rarely accepting the first, thus very slowly recovering, but in busy
periods it never recovered.
