[asterisk-users] Asterisk not sending RTP

[Nir Simionovich]

I've now also enabled RTP debugging, and noticed that Asterisk doesn't
send out RTP at all.
All the lines appear as the following:

Got RTP packet from 62.219.61.73:59436 (type 0, seq 1243, ts -1997588432,
len 80)

Any ideas anyone ?

Hi Matt,

  I'm dumping only the eth0 interface, as this is the only interface
configured on the box,
eth1 is disabled. IPtables is completely disabled on the server, so that
is not the issue.
SIP invites appear to be handled correctly and being sent in and out
correctly.

  Other than that, I'm fairly baffled.

Are you dumping just one ethernet card?

Is it possible it's trying to send out the other?

What do you have in the way of a firewall?

Do you have iptables rules?

Does the SIP protocol get sent?
