Prezados membros da lista,

Depois de ter configuardo uma TE420 com 3E1s, consigo receber ligações
normalmente sem dificuldades. Como vocês podem observar no log abaixo


  -- Executing [5908 em from-pstn :1] NoOp("UniCall/14-1", "Catch-All DID Match
- Found 5908 - You probably want a DID for this.") in new stack
    -- Executing [5908 em from-pstn:2] Goto("UniCall/14-1", "ext-did|s|1") in
new stack

    -- Executing [h em ivr-3:1] Hangup("UniCall/14-1", "") in new stack
    -- Hungup 'UniCall/14-1'
    -- Unicall/14 released


Mas agora estou com problemas para realizar as ligações utilizando a
libunicall. O problema fica muito claro nesta linha do log:

[Dec 13 10:03:54] ERROR[12935] chan_unicall.c: Unicall/1 protocol error.
Cause 32776

Pesquisando na internet descobri que trata-se de "Seize ack timed out", já
tentei de várias formas contornar esta situação. As versões de software que
estou utilizando são ( http://www.voip-info.org/wiki/view/Asterisk+MFC+R2).

asterisk-1.4.9
spandsp-0.0.4
unicall-0.0.5pre1
zaptel-1.4.4

Minhas alterativas para corrigir o problema já foram:

Adicionar a linha:
protocolvariant=br,20,4,x,max-seize-wait-ack=3000

Confome orientações do Moises Silva:

This deserves a little bit of more explanation.

br = Brazil
20 = ANI digits
4 = DNIS digits
x = this is just a hack to be able to work with defaults and specify
the next value. protocolvariant expect here a mask of values ( an
integer ), passing NOT an integer but a character x will cause the
defaults to remain.
max-seize-wait-ack = Number of milliseconds to wait for the ACK.

Incrementei o valor do wait até 50000 (50 segundos) Realmente faz efeito, o
valor passado é respeitado, mas após esgotar-se o tempo o mesmo erro
é reportado.

Alterei no código fonte (mfcr2.c) os defines:

#define DEFAULT_T1                                         15000 para 25000
#define DEFAULT_MAX_SEIZE_ACK_WAIT         2000 para 6000


De fato alterar o define MAX_SEIZE_ACK_WAIT tem o mesmo efeito que passar o
argumento max-seize-wait-ack=XXXX na linha da variável protocolvariant.

Estou usando o FreePBX com um Custon Trunk (Custon String Dial: UniCall/g1),
meu extensions_aditional tem as entradas "OUT_3 = AMP:UniCall/g1" e
"OUTMAXCHANS_3 = 10".

Alguem Já passou por um problema como esse ? Eu ficaria grato seu alguem me
indicasse alternativas para resolve-lo.
