receiving "503 Service not available" response.

What does your dialplan look like?

A bridge with a 503 reply will fail. If FS is sending another INVITE that
suggests it's doing another bridge when the first fails.

Hi,

I have this scenario:

Proxy - FS -- LCR

I make a call from an user register in my proxy, passing trough freeswitch
( for media transcoding) , to my LCR server.

The LCR looks for one route for my call, but I doesn't found any, so It
replays "503 Service not available, no more gateways".

When FS receives this response , *it sends a re invite* to the LCR server,
falling again in the same error reply.

In my case I don't what FS to send the re invite , I need it to pass the
reply ("503 Service not available, no more gateways") to the proxy.

How can I manage this?

Regards,

Camila
