Algumas aplicações requerem um ajuste no dialplan do gateway. Por padrão, o gateway exige que se disque um prefixo para acesso à portas. O dialplan que segue torna isso transparente, ou seja, a associação das contas às portas se dá automaticamente conforme configurado pela interface WEB:

static=yes
writeprotect=no
autofallthrough=yes
clearglobalvars=no
priorityjumping=no
