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.
