Thank you Luciano for your answer but doesn't it still work me, do the calls enter me
of the pstn and don't I listen anything... where I can look for? , there will be some
of form so that the IP of where the calls come from
asterisk does not use mediaproxy, somebody has an example.
any help is appreciated..
thank you

Subject: Re: [Kamailio-Users] I don't have asterisk audio to openser - mediaproxy
Hi Ricky,
I think you should increase the mediaproxy natping interval to 30 and then add
use_media_proxy() line after you setflag(6). check below:---
##Detect requests in the dialog behind NAT and flag with 6
if(nat_uac_test("19") || search("^Route:.*;nat=yes")){
append_hf("P-hint: LR|fixcontact,setflag6\r\n");
fix_contact();
setbflag(6);
USE MEDIA PROXY HERE---> use_media_proxy();
};
route(1);
} else {
sl_send_reply("404", "Not here");
}
exit;
}
