[asterisk-users] Request for some help....

[K.N.Arun Kumar]

Hi,

   I am working out to establish calls between two asterisks PBX'es using H323 channels. I am using SJ phones as the H323 clients.
   The scenario looks like,
  
   SJ phone(444) --- Asterisk PBX 1 --- H323 channel --- Asterisk PBX2 --- SJ phone(555). 

I was able to make the calls and channel was successfully established. At both the SJ Phones it displays call is operational.
But the voice is not getting transmitted, I  was not able to hear anything at both the ends. Two asterisks are on machines 10.238.115.223 & 10.238.115.224, two clients are on the machines 10.238.115.226 and 10.238.115.230. I am including the H323.conf and extensions.conf of both the asterisks.
Can someone kindly help me out to carry my work further.

H323.conf (Asterisk 10.238.115.223)

[general]
port = 1720
bindaddr = 0.0.0.0
allow=alaw
allow=ulaw

gatekeeper = DISABLE

AllowGKRouted = yes
context=default

;alias definition

extensions.conf (Asterisk 10.238.115.223)
