[Asterisk-Users] Asterisk and Cisco CallManager Integration

Sat Jul 9 09:01:02 MST 2005

Hi again,

Well, thanks for the details steps. But before I received your mail I had
already installed Asterisk at Home v.1.3 and updated it with OH323 add-on. It
is a zip file which when you install you get all the libraries installed and
compiled for you.

Now, one last step for me which I need your help all with. What is needed to
get the CCM and Asterisk to exchange calls over H323? I mean which config
files needs to be updated. I now have oh323.conf shown and ready.

Thanks
Walid

The below worked for me to integrate with CCM.

pwlib-v1_6_6

openh323-v1_13_5

asterisk-oh323-0.7.1

The only change I made was

  ----------------------------------------------------------

  Remove the line 433 (:protected) in  /usr/src/openh323/include/gkserver.h

  else you would get the below error during compilation

  /usr/src/openh323/include/gkserver.h:434: error: `virtual

  H323Transaction::Response H323GatekeeperRRQ::OnHandlePDU()' is protected

  ----------------------------------------------------------

Steps to follow:

-----------------------

To enable H323 for inter-op with Cisco Call Manager (H.323)

  cp pwlib-v1_6_6-src.tar.gz openh323-v1_13_5-src.tar.gz

     asterisk-oh323-0.7.1.tar.gz /usr/src/

  cd /usr/src

  tar zxf pwlib-v1_6_6-src.tar.gz

  tar zxf openh323-v1_13_5-src.tar.gz

  tar zxf asterisk-oh323-0.7.1.tar.gz

  -----------------------------------------------------

  Set Environment variables

  PWLIBDIR=/usr/src/pwlib

  OPENH323DIR=/usr/src/openh323

  LD_LIBRARY_PATH=/usr/src/pwlib/lib:/usr/src/openh323/lib

  --------------------------------------------------------

  cd /usr/src/pwlib

  ./configure

  make opt

  cd /usr/src/openh323

  ./configure

  ----------------------------------------------------------

  Remove the line 433 (:protected) in  /usr/src/openh323/include/gkserver.h

  else you would get the below error during compilation

  /usr/src/openh323/include/gkserver.h:434: error: `virtual

  H323Transaction::Response H323GatekeeperRRQ::OnHandlePDU()' is protected

  ----------------------------------------------------------

  make opt

  cd /usr/src/asterisk-oh323-0.7.1

  Edit makefile and set the paths/options according to your system.

  Type "make" to build the oh323wrap library and the

  ASTERISK OH323 channel driver.

  -------------------------------------------------------------

  If compiling fails, then change the makefile to reflect the below

CPPFLAGS=$(OPENH323FLAGS) -DP_USE_PRAGMA -ffunction-sections -fdata-sections

-D_REENTRANT -Wall -fPIC -I/usr/src/pwlib/include -DPTRACING

-I/usr/src/openh323/include -DHAS_OSS  -Wall -x c++ -Os

 ---------------------------------------------------------------

  Type "make install" to install the binaries. This will also

  install a sample configuration file, if there isn't one.

  Next, add to your LD_LIBRARY_PATH the path where the oh323wrap

  library was installed (or edit your /etc/ld.so.conf file, add

  the library path, and run "ldconfig").

Thanks,

~Vamsi
