[Asterisk-Users] Call Error

[Mireia.Munoz-de-jesus at ifaedi.insa-lyon.fr]

When I try to make a call, I have this error:

dial 06302 at gatekeeper
    -- Executing Dial("OSS/dsp", "OH323/06302|20|tT") in new stack
*CLI> WrapH323Connection::WrapH323Connection: WrapH323Connection created.

Can Someone help me?

In extension.conf I have written :
exten => 06302,1,Dial,OH323/06302|20|tT

Thanks for all your help.
