Cisco AS5300 - transcoding ulaw na g729

Wiadomość

pretenderek · #1

Witam,

Jestem od niedawna w temacie voice na Cisco ale
chcialbym skonfigurowac Cisco AS5300/4xE1
IOS (tm) 5300 Software (C5300-JK8S-M), Version 12.2(10a)
z Asteriskiem w taki sposob aby miec mozliwosc zmiany voice codeka z np. ulaw na g729.

Scenariusz dzialania jest taki:
SIP numer 1111(kodek ulaw) zarejestrowany pod Asterisk dzwoni na numer 1234, rozmowa kierowana powinna byc na port E1 serial 0 w cisco, nastepnie kierowana na serial 1 E1 i spowrotem do Asteriska na numer 2222. Porty E1 serial 0 i serial 1 spiete sa kablem (loopback).

Czy ktos z mogłby pomoc z taka konfiguracja?

Pozdr,
P.

A może pokarz co już zrobiłeś to ci podpowiemy? Tak będzie łatwiej

Z tego co czytalem to aby zmianić codec z ulaw na g729 to musze przepchać rozmowę przez E1 - serial0->serial1 dokonujac transodingu. Oba porty mam połaczone kabelkiem, który jest zarobiony zgodnie z: 1 -> 4, 2 -> 5, 4 -> 1, 5 -> 2.

Ponadto:

Kod: Zaznacz cały

    Layer 3 Status:

    Active dsl 1 CCBs = 0
    The Free Channel Mask:  0x7FFF7FFF
    Number of L2 Discards = 0, L2 Session ID = 113

Zastanawia mnie tez taka sprawa, że Layer 2 Status zmienia się co chwile z TE1_ASSIGNED na AWAITING_ESTABLISHMENT. Nie wiem czy tak powinno być.

Dodatkowo jak już dzwonie z konta SIP z numeru 1111 (zarejestrowany pod asterisk) na nr 1234 to komenda:

przepraszam, zamiast Originate 6666 jest Originate 2222.
Nie ten fragment skopiowałem.

No ale masz głosową E1, więc jak chcesz tam mieć kodek G.729? Po drugie do transkodowania musisz mieć DSP.

to jak ugryźć ten temat ?

1) konfig nie jest cały a jak zapewne wiesz forumowicznie nie wroza z fusów
2) nie widze wpisow mowiacych o partycypacji poszczegolnych voice-portow w dsp sharingu
(network participate)
3) nie widze to czego synchonizujesz zegar (network clock select)
4) nie widze ustawien voice-card mowiacych o dsp-farmingu (E1 masz 4 a tylko 60 DSP)

stad nie moge pomoc...

Powyżej mój konfig. Nie mam nic ponadto.
Jak wspominałem jestem od niedawna w VOICE na Cisco.
Prosiłbym o pare informacji od czego zacząć.

Uwagi:
- E1 0 daje zegar, E1 1 bierze
- nie wiem jaki masz adres * więc wpisałem X.X.X.X
- call wchodzi z * z DNIS 1234 i na wyjściu do E1 0 translowany jest na 2222
- sprawdź najpierw czy wstaną Ci porty ISDN:

bez tego nie będą banglały calle
