[Serusers] Ser - Asterisk small problem

[karim basraoui]

Hi,

I am using an architecture with Ser and Asterisk.

When Ser forwards the calls to asterisk, everything is all right. the caller
has a "ringing" message and the callee rings.

when the callee picks up, the caller has a "connecting" message but the
callee hungs up suddenly.

my asterisk shows the message:  -- Got SIP Response 503 "server error" back
from Ser_ip --

how can i tell to asterisk to setup the call ?

thank you !
