[asterisk-users] Asterisk to CCM

[Dan Austin]

Make sure you are stripping the 8 on inbound calls to that H323 gateway
under CCM and that it has a valid search space to find your extensions...

Subject: [asterisk-users] Asterisk to CCM

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+Integration.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<mailto: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<mailto: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
