Re: [SR-Users-ES] No Audio con clientes detras de una NAT, el audio funciona con clientes que usan IPs publicas (Estoy utilizando rtpproxy)

Hola, este es mi primer post en esta lista, Tengo instalado el kamailio 1.5.1 y estoy utilizando un kamailio.cfg utilizando el que trae por defecto, luego he modificado el cfg para activar mysql, domain, presence, nathelper y authentication con md5, todo funciona como se supone que deberia, los clientes pueden registrarse, enviar mensajes de texto y hablar entre ellos. El unico problema es el audio cuando dos clientes estan detras de una NAT, los telefonos pueden realizar la llamada y suena el ring, pero cuando se descuelga no hay audio en ninguna direccion. cuendo los telefonos tienen una IP publica todo funciona bien, tambien funciona cuando utilizo un Linksys PAP2T con las opciones "Insert VIA received", "Insert VIA rport", "Handle VIA received", "Handle VIA rport" y "NAT mapping enable" encendidas, con el softphone de Qutecom stambien funciona. Este problema me esta sucediendo con los telefonos fisicos Thomson phones (model ST 2022) y GrandStream Budge Tone 200, este problema ocurre sin importar que opciones le coloque para el tipo de nateo dentro de los telefonos, Incluso he utilizado stun con stunserver.org o con el servidor de stun de ekiga, los telefonos se registran y pueden hacer y recibir llamadas, pero no hay audio cuando atiendes la llamada. Con kamctl ul show, puedes ver que han registrado el Contact con su IP local y el Received con la IP publica y los puertos para el NAT La unica diferencia con los Linksys que si funcionan es que los Linksys registran el Contact con la IP publica. Aqui se puede ver dos telefonos con NAT en el proxy Domain:: location table=512 records=2 max_slot=1 AOR:: 20000004(a)212.4.107.250 Contact:: sip:20000004@192.168.254.110:5060;transport=udp;user=phone Q= Expires:: 1150 Callid:: 72ed03f6d2f390f9(a)192.168.254.110 Cseq:: 10003 User-agent:: Grandstream BT200 1.1.6.27 Received:: sip:212.4.97.115:35379 State:: CS_NEW Flags:: 0 Cflag:: 0 Socket:: udp:212.4.107.250:5060 Methods:: 7807 AOR:: 20000000(a)212.4.107.250 Contact:: sip:20000000@192.168.254.101:5060;user=phone Q= Expires:: 2945 Callid:: 17fe-c0a80101-5-1(a)192.168.254.101 Cseq:: 6 User-agent:: THOMSON ST2022 hw2 fw3.56 00-18-F6-B5-7E-06 Received:: sip:212.4.97.115:55128 State:: CS_NEW Flags:: 0 Cflag:: 0 Socket:: udp:212.4.107.250:5060 Methods:: 4294967295 Estoy utilizando rtpproxy y no hay ningun error en el log que indique que el rtpproxy no esta funcionando, de hecho haciendo un SIP trace muestra al rtpproxy seteando puertos para el audio.
