TSILO - transaction is not suspended - sr-users

6 Jan 2021

Hi,

What happens in the route[RELAY]?

Maybe code after "route(RELAY)" is not executed?

When there is only 1 device what value is inside $var(hstored)
when the register hits Kamailio?

    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.
