[OpenSIPS-Users] delete a binding in location database from the routing script

With Opensips we can use timeout, for example after sending an INVITE if we
do not receive any provisional responses after 32 seconds, this
registration binding should be refreshed / recreated.

Some equipments are generating 503 when they face a transport layer
failure, we found out that this is quite reliable.
In our case it would be best to delete the binding to avoid loosing time
trying to use when we know is is not working.

Is there a way to detecting transport layer failure in Opensips ?  (TCP RST) Transaction Layer Errors

   In some cases, the response returned by the transaction layer will
   not be a SIP message, but rather a transaction layer error.  When a
   timeout error is received from the transaction layer, it MUST be
   treated as if a 408 (Request Timeout) status code has been received.
   If a fatal transport error is reported by the transport layer
   (generally, due to fatal ICMP errors in UDP or connection failures in
   TCP), the condition MUST be treated as a 503 (Service Unavailable)
   status code.
