asterisk users - Feb 2005 - X-lite to Cisco ATA - no RTP

Hi there,

I have X-lite and a Cisco ATA on the same hub (i.e. no NAT, no ACLs) as
my Asterisk box.

Ethereal shows normal SIP signaling when I call from X-lite to the ATA.

Ethereal also shows RTP is passed from X-lite to Asterisk, and RTP is
passed from the ATA to Asterisk, but no RTP from Asterisk to either
device.

(Note that Ethereal does show the SIP signaling packets originating from
Asterisk, so nothing funky with my Ethereal filter either)

Has anyone run into anything similar? Any pointers? I set up all the
extensions using AMP.

If you need specific configs, I am happy to provide.

Cheers
Keith.

Interesting, SUSE firewall allows SIP but not RTP out of the box.
