+		<para>
+		The <emphasis>use_single_process</emphasis> parameter controls whether the HEP message processing is
+		handled by the SIP worker that is processing the message or by a dedicated HEP worker process.
+		When this parameter is set to <emphasis>1</emphasis>, the HEP worker process is created to handle all HEP message
+		transmissions. This allows OpenSIPS to offload HEP transmissions to a separate process, freeing up the SIP workers.
+		</para>
+		<para>
+		In this case, the HEP worker process will queue the unsent HEP messages and attempt to send them periodically.
+		If the messages cannot be sent, they are retained in a job list that can be configured through the 
+		<emphasis>max_number_of_jobs</emphasis> and <emphasis>max_keep_time_job</emphasis> parameters.

+		The <emphasis>max_number_of_jobs</emphasis> parameter defines the maximum number of HEP message jobs that can be stored in

+		new incoming job.
