VoIP

Hello there comrades,

I?m interested to familiarise with techniques, ideas and tools related to VoIP 
testing. This is a brand new area for me, and my short research yielded only a 
couple of tools such as VOMIT and VoIPong. 
As a matter of fact, I?m not sure which should be the ?scope? of a 
comprehensive VoIP test, and have not come across any methodologies of this 
type. 
Assume that an ISDN / VoIP router is configured to deny incoming connections 
form arbitrary telephone numbers. I would be particularly interested to see if 
there is a possibility of bypassing such defence mechanisms, perhaps by 
disguising into a ?trusted? telephone number, or by other means. 
I?d be very glad to receive feedback/ideas on these issues

Thanks, 
Stelios.
