[AsteriskBrasil] SIP Algar vs Asterisk

[Guilherme Rezende]

     Pessoal, estou enfrentando problemas no SIP-Trunk c/ Algar.  O 
Asterisk está alarmando sempre, se deslogando e logando novamente.  
Estou usando codec g729 e existe uma banda garantida de 512kbps.  Veja 
abaixo os warning´s no Asterisk:  Algo que passa fazer p/ melhorar 
isso?  Abaixo configuração da conta e log do Asterisk.
Obs.: Existe mais de uma conta configurada no meu asterisk.
