[Asterisk-Users] SIP (peer to peer?)

You're right for pure SIP configurations , but Asterisk acts here as "media gateway" and treats all of the media comm. e.g. to eventually communicate with other types (like PSTN, H323, AIX, ... the voicemail app.)

 Hi all,

Has anyone have an idea why, if you capture the files on a Asterisk network (ex with Ethereal) you always see the communication between the two sip phones( hard or soft) passing through the asterisk server (on UDP layer) 

Isn't SIP a protocol that (after that it has established the call) , he connects the two users with each other?


Maybe a stupid question, but I'm not a SIP expert.


Thank you for your help.
