[SR-Users] TSILO - transaction is not suspended

[Jeremy McNamara]

Hi Folks - I am attempting to set up a mobile push configuration, by
following the published example(s).

If we have more than one endpoint registered, this configuration works as
expected (via the ts_store() path below).

If we do not have another registered endpoint the transaction seems to be
suspended but then cannot be resumed (t_suspend) after REGISTER arrives.
