asterisk users - Nov 2005 - Infinitum bloquenado SIP ???? / Is Infinitum blocling SIP ????

Hola lista:
  Para todos los de Mexico, desde hace aproximidamente 2 meses, estoy
teniendo problemas con
la trasmicion de voz via protocolo SIP. Entre Infinitums o desde Infinitum
hacia otros provedores.
  Alguien mas esta experimentando esto ??? par poder corroborar que Telmex
este bloqueando el
protocolo SIP ?...
  Por que el protocolo IAX2 funciona a la perfeccion.
  Nota: Si se firman los equipos mas no viaja la voz despues de eso.
  Espero respuesta....
  Hi list
  I'm having problems here in Mexico, connecting SIP devices via Infinitum
ISP, as i see the ISP is
blocking the SIP traffic.
  I want to knwo if any one is having this problem also. So i can confirm
that Infinitum is doing this.
  Note: The devices get register but they can't send any more data as dialed
number or voice.
 Thanks

Hi Alvaro.
 
What Ive noticed is that telmex has been blocking not sip traffic but rtp
traffic in my case. Sip phones can connect to my asterisk box but after a
call is established, no voice comes back or forth. I have the same config on
an outside box in the US and everything works perfectly.
 
Both boxes are working as gateways and firewall and they have the same
iptables rules so I know it is not a firewall related issue since the box in
the US works great. 
 
I guess telmex is doing something...
