[Asterisk-Users] SIP Proxy and use with Asterisk

[steve]

Hi Everyone:

 

I have a THREE questions.  What is a sip proxy and what is the benefit of
having one with Asterisk?   I am well aware that we have a sip channel in
Asterisk and that we have SIP registration.   I am not sure why you would
need a SIP server and OR a registration server.

  

 

Second question, with Asterisk are you able to do video on VOIP video
phones?

 

 

Last question, does iptel.org SIP Express Router work with Asterisk?

 

 

Thanks
