[AsteriskBrasil] Problema com Telefone Voiper da Intelbrás

[Junior Polegato - Asterisk]

Boa tarde!

       Pessoal, estou tendo um probleminha que começou final da semana 
passada e hoje já ocorreram várias vezes. Aparece no CLI do Asterisk 
1.2.13~dfsg-2etch4.1 a seguinte mensagem:


Mar 18 13:58:33 NOTICE[27276]: chan_sip.c:3989 copy_via_headers: No 
header field 'Via' present to copy


       Deixei rolar e assim ficou aparecendo essa mensagem umas 6 a 8 
por segundo por quase 3 horas, totalizando mais de 70.000 mensagens, 
quando recebi:


Registered SIP '1022' at 10.9.8.22 port 5060 expires 60


       Não consegui pegar o pacote SIP, mas na próxima vez que tiver o 
problema vou pegar. Dando um "sip show peers", aparece:


Name/username              Host            Dyn Nat ACL Port     Status 
. . .
1022/1022                  (Unspecified)    D   N      0        UNKNOWN
. . .


       No telefone está apenas o codec G729 e no sip.conf:

[general]
context=ramais
bindport=5060
bindaddr=10.9.8.254
srvlookup=yes

register => <num_azzu>:<senha_azzu>@<serv_azzu>/<num_azzu>

. . .

[1022]
type=friend
username=1022
secret=<rsrsrs>
host=dynamic
callerid="Voiper - 1022" <1022>

       Reparei que o problema começa depois de:

    -- Called 3941xxxx em azzu
    -- SIP/azzu-0818a2e8 is ringing
    -- SIP/azzu-0818a2e8 is making progress passing it to SIP/1022-081bdf90

       A chamada:

exten => _[0-6]XXXXXXX,1,Macro(saida_azzu,${EXTEN})
exten => _[7-9]XXXXXXX,1,Macro(saida_celular,${EXTEN})
exten => _XX[0-6]XXXXXXX,1,Macro(saida_azzu,${EXTEN})
exten => _XX[7-9]XXXXXXX,1,Macro(saida_celular,${EXTEN})



       Alguém já teve problemas assim? Tem alguma solução?


       Grato.
