Atualmente, estou tentando federar dois domínios do Lync com um proxy SIP personalizado no meio. O problema é que o servidor front end responderá "413 - Entidade muito grande" para assinar solicitações provenientes do outro domínio do Lync depois de passar pelo proxy.
No entanto, quando eu enviei uma mensagem semelhante com o SIPp, um emulador SIP, o cadastro é aceito mesmo que tenha passado pelo proxy.
As duas mensagens são muito parecidas. O proxy adiciona uma rota de registro e acrescenta um ID no final da tag De. Ele não consegue colocar as mãos no corpo.
A diferença de tamanho do conteúdo é porque o SIPp adiciona um CRLF no final do corpo, o que o Lync não faz.
Não consigo ver nada de errado com a solicitação. As seguintes mensagens foram registradas no Lync Edge do domínio de destino.

Alguém sabe o que pode acionar esse erro? A mensagem de erro não é realmente de grande ajuda aqui ...
Alguma ajuda seria muito apreciada!
