[Serusers] Is RTPproxy needed even when there is a Cisco PIX?
by Ricardo Carvalho 13 Jul '06

13 Jul '06

Hi, I'm deploying a VoIP server using SER and I would like to know if I need to install RTPproxy (or Mediaproxy), because the network where the server will be placed already has a Cisco PIX 515E which has this feature that analyses headers of SIP messages and I suppose that rewrites them to avoid NAT problems. Regards, Ricardo.

RE: [Serusers] prevent INVITE without REGISTERing

H i, Thanks for your answer. I see in my logs that both %$registered_host and %si are same but if (!avp_equals_xl("$registered_host", "%si")) fails ! I also tried : if (!avp_equals_xl("%$registered_host", "%si")) But it also failed. Any idea why ? Could it be that they are different types of variables ? IP address and text ?
