[asterisk-users] Asterisk & CME integration using h323

[Enrico Pasqualotto]

Hi all, I'm trying to trunk my asterisk with a cisco cme 3.3 using h323.

Cisco conf:

dial-peer voice 8 voip
  destination-pattern 2...
  session target ipv4:<asterisk ip>
  codec g711alaw
  no vad

h323.conf

[general]
port = 1720
bindaddr = 0.0.0.0
;tos=lowdelay
;
disallow=all
allow=alaw
allow=ulaw
allow=gsm
context=from-internal

extension.conf

[from-internal]

exten => _1XXX,1,Dial(SIP/${EXTEN}@<cme ip>)
exten => 2000,1,Dial(SIP/2000)

I'm able from Asterisk to call ip phone connected to cme but from cme to 
asterisk the phones ring but go in hangup immediatly.

My debug:

I don't understand why the call goes down only from cisco to 
asterisk.... any ideas?


Thanks Enrico
