Hi, 
I configure SIP2 , and the service load well
root@srvcbkohac01:/var/log/koha/catalogo# netstat -an | grep ":8023"
tcp        0      0 0.0.0.0:8023            0.0.0.0:*               LISTEN    
root@srvcbkohac01:/var/log/koha/catalogo# netstat -an | grep ":6001"
tcp        0      0 0.0.0.0:6001            0.0.0.0:*               LISTEN    
root@srvcbkohac01:/var/log/koha/catalogo# koha-sip --status catalogo
[ ok ] SIP server running for catalogo:.


My selfchek machines are not connecting to SIP server. And if i want to try do telnet localhost 6001 the server open an closes the connection inmediately

root@srvcbkohac01:/var/log/koha/catalogo# telnet localhost 6001
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
Connection closed by foreign host.


cannot permit any command. 

My server is Debian "Debian GNU/Linux 10 (buster)", and the firewall its not enabled.

My server params an port are the following, those are working fine inkoha version 3.22:

  <server-params
    min_servers='10'
    min_spare_servers='5'
    log_file='Sys::Syslog'
    syslog_ident='koha_sip'
    syslog_facility='local6'
    ipv='4'
  />
 
  <listeners>

    <service
      port="8023/tcp"
      transport="telnet"
      protocol="SIP/2.00"
      timeout="120" />


    <service
      port="6001/tcp"
      transport="RAW"
      protocol="SIP/2.00"
 client_timeout="600"
      timeout="600" />



Really appreciate if have any idea ...

Humberto
