[asterisk-users] Asterisk to CCM

[Jimmy Ezell]

Hit another problem in my tutorial in converting over from Cisco
CallManager to Asterisk. 
I have been following the instructions at :
http://voip-info.capatres.com/wiki/view/Asterisk+Cisco+CallManager+Integ
ration.html on intergrating Asterisk and Cisco CallManager.  
I can make calls from CCM to Asterisk phones - and yes that felt good to
get that working.
My problem is that it does not work from the other direction.   I cannot
make calls from CCM phones to Asterisk Phones.  
I want to be able to dial 8 and the extension of the ccm phone.
I am using CCM 3.3.(5) so I do not have the option to use a SIP turnk
because it is not supported.  I am also using h323 instead of ooh323.
Not sure if that might make a difference.
 
In Asterisk console I get:    
 
-- Executing [8207 at internal:1] Dial("SIP/207-08bd64c8",
"H323/callman02/207 at 172.16.200.10:1720") in new stack
    -- Requested transfer capability: 0x00 - SPEECH
    -- Called callman02/207 at 172.16.200.10:1720
  == Everyone is busy/congested at this time (1:0/0/1)
 
 
This is the contents of my h323.conf file:
=================
[general]
port = 1720
bindaddr = 172.17.100.2 
disallow=all
allow=gsm               ; Always allow GSM, it's cool :)
allow=ulaw              ; see doc/rtp-packetization for framing options
allow=alaw  
dtmfmode=rfc2833
gatekeeper = DISABLE
context=default

[callman02]
type=friend
context=default
ip=172.16.200.10
port=1720
disallow=all
allow=gsm       
allow=ulaw             
allow=alaw           
dtmfmode=rfc2833
nat=no
canreinvite=yes
qualify=yes

 
extensions.conf file
==============
[globals]
CISCOTRUNK=H323/callman02

[cisco]
exten => _8XXX,1,Dial(${CISCOTRUNK}/${EXTEN:1}@172.16.200.10:1720)
exten => _8XXX,n,Congestion()
exten => _8XXX,n,Hangup()
