NOS sip – Asterisk FreePBX

Primeira tentativa de ligar o asterisk com o freePBX ao Serviço SIP voip NOS PHONE.

Configurações do SIP Trunk No Asterisk FreePBX

PEER Details

SIP Settings – Incoming

USER Context

USER Details

1290XXXXXXXXX:PASSWORD@193.126.31.5

UPDATE: Após várias tentativas com alguns dados recolhidos consegui registar o asterisk no nos phone com simples string:

1290XXXXXXXXX:PASSWORD@193.126.31.5

(Old: 1290XXXXXXXXX@XXXXXXXXX.zpe.voxis.zon.pt:PSWD:1290XXXXXXXXX@XXXXXXXXX.zpe.voxis.zon.pt)

A alteração foi efectuada na configuração Incoming do Trunk.

Em relação ao peer (para fazer chamadas) continua a registar mas não consigo realizar a chamada, que aborta com o seguinte erro:

chan_sip.c:23840 handle_response_invite: Received response: “Forbidden” from …

UPDATE: Algum tempo depois a tentar mais um leque de possibilidades acho que consegui avançar mais um pouco. Já consigo fazer chamadas para fora. Mas ao contrario dos outros trunks só tenho voz num sentido.

A alteração foi efectuada na configuração Outgoing do Trunk.

Bastou adicionar: fromuser=1290XXXXXXXXX

Após um tempo acaba por cair a chamada e exibir o seguinte erro:

check_rtp_timeout: Disconnecting call ‘SIP/nostrunk-0000016e’ for lack of RTP activity in 31 seconds

UPDATE: Após uma ajuda de um membro do forum zwame, que indicou as seguintes outgoing configurações como funcionais:

username=1290XXXXXXXXX
type=peer
secret=PASS
host=193.126.31.5
fromuser=1290XXXXXXXXX
fromdomain=193.126.31.5
directmedia=yes

Experimentei e conclui que tinha passado a ter audio nos dois sentidos, mas tinha perdido a capacidade de obter as chamadas externas para o meu número. Concerteza que existia algo nesta configuração que fazia falta na que estava a usar. As unicas coisas a mais eram:

fromdomain=193.126.31.5
directmedia=yes

A alteração foi efectuada na configuração Outgoing do Trunk.

Adicionei-as e ficou funcional.
