Hi list,

I am configuring CGRateS with kamailio 4.4 using deb packages on debian 8.

I am facing a issue while processing event_route[dialog:start] for answering call INVITE at
evapi_async_relay("{\"event\":\"CGR_CALL_START\",

with following error

/usr/sbin/kamailio[13887]: ERROR: evapi [evapi_mod.c:288]: w_evapi_async_relay(): failed to suspend request processing

However, after discussion with Dan on IRC i replaced function evapi_async_relay() with evapi_relay() resolved the issue.

Whats causing this error?

Can anyone suggest some way out for keep using evapi_async_relay?

event_route[dialog:start] is executed when 200ok response for INVITE is received, so there is no SIP request to suspend at that time. Using evapi_relay() should be fine in my opinion here.

There is support to suspend routing of sip responses as well, but not sure if it is really useful in this case, you just need to notify cgrates that the call has started, no reason to wait for a reply from cgrates before forwarding the sip response.

Note that evapi_relay() is not blocking the sip routing, so it terms of performances is in pair with async option.

Cheers,
Daniel
