Hello
In this scenario, customers behind NAT register in kamailio, records are stored in a db etc. Kamailio uses Asterisk boxes as gateways to send calls to PSTN. Is it possible to use Asterisk as the media server instead of media-proxy or rtp-proxy? In this case the SDP that Asterisk sends in the 180 message needs to me modified?
thank you

No, nothing needs to be modified.
However, in this scenario you are limited to Asterisk's performance characteristics in terms of the number of concurrent calls that can be handled. Just about any media relay will be much more scalable and lightweight.
Asterisk is a PBX and a nice feature server. You don't build SIP service delivery platforms out of Asterisk used as a general-purpose call router.
