[Asterisk-Users] Asterisk H.323 channel...

[Hello World]

Hi all,

  I am trying to use a "Siemens optiPoint 300" IPPhone (H.323 only) with Asterisk (1.0-RC2).

  So far I have been using the H.323 channel included in the tarball (Nufone ?).

  I encountered a strange behaviour when I try to make a call from the IPPhone to my Asterisk box :

    =====> here is the H.323 configuration for the incoming calls (192.168.1.50 is the IP of the Siemens phone) :

[Damien]
type=user
host=192.168.1.50
context=incoming

    =====> the incoming context has a single extension :

[incoming]
exten => 666,1,Playback(demo-echotest)
exten => 666,2,Echo                     
exten => 666,3,Playback(demo-echodone)  

  =====> the IPPhone is configured to use the Asterisk box as a H.323 gateway (system type = "Gateway" / IP address of the gateway = IP address of the Asterisk box)

  =====> when I dial "666" on the IPPhone Asterisk seems to answer the call then 2 seconds later it hangs up :

  Any idea about this "H245    Read error: Interrupted system call" that appears in the debug messages ???

Thanks, Damien.


BTW, the H.323 channel has been compiled with the recommended PWLib 1.5.2 and OpenH323 1.12.2.
