(Non-critical Response)

how to fix the problem????




i am configure ser:

if (method=="INVITE") {
  if (uri=~"sip:1[1-9][0-9]+ at .*") {
     rewritehostport("192.168.0.183:5080");
  };
};

an asterisk:

sip.conf
; config Xlite
[1234]
;context=sip
context=from-ser
type=friend
auth=md5
username=1234
secret=chooseapassword
;fromdomain=sorcier.com.pe      ; para prueba de ser -asterisk
callerid="First Extension" <1234>
host=dynamic
canreinvite=no
;disallow=all
;allow=gsm
;allow=ulaw
;allow=alaw


;and conexion the ser to asterisk
;
[ser-sip]
type=friend                ; permitimos llamadas entrantes y
salientes. Usar peer si solo es MWI
context=ser-asterisk               ; este es el contexto que usan las
llamadas entrantes
;host=sorcier.com.pe       ; Este es tu hostname o IP del servidor SER
host=192.168.0.183
fromdomain=sorcier.com.pe  ; este es tu  SER_DOMAIN (nombre de dominio del SER)
;insecure=very              ; Permite que las llamadas que viene del
SER pasen a Asterisk
insecure=yes
;mailbox=user at context      ; esto es para listar las cuentas de voicemail


;i am copy the voip-info



and the file the extensions.conf
; Configuracion al servidor ser, para llamada de ida
[from-ser]
exten => _X.,1,Dial(SIP/${EXTEN}@${SERADDRESS},20,tr)

[ser-asterisk]
; Ignora el dígito 0
;ignorepat => 0
; conexion a un telefono sip

exten => _1X.,1,Dial(SIP/${EXTEN})
