Asterisk Doesn't see the OKs?

Ok, I understand.

The firewall is disabled right now.

I’m tired…

22

Explain your setup

IE number of ethernet interfaces, are you using aliases ? what sip is bound to in sip.conf and what localnet and externip is set to.

Asterisk ----------------- Iplan (Provider)
200.xxx.xxx.87 190.xxx.xxx.165

Extension 6000
200.xxx.xxx.85

I’m not using aliases, there is no firewall (I disabled it), I’m not using NAT because both of IP are public.

Sip.conf

[6000]
type=friend
secret=6000
record_out=Adhoc
record_in=Adhoc
qualify=no
port=5060
pickupgroup=
nat=no
mailbox=6000@device
host=dynamic
dtmfmode=rfc2833
dial=SIP/6000
context=from-internal
canreinvite=no
callgroup=
callerid=device <6000>
accountcode=
call-limit=50

[IPLAN]
host=190.xxx.xxx.165
type=peer
insecure=port,invite
disallow=all
allow=ulaw
allow=alow
nat=no
dtmfmode=rfc2833

So, I made the update to Asterisk 1.6.0.1 and the same thing happens…

I made a capture with ethereal from Asterisk, and it’s give me BAD CHECKSUM on INVITE… Why is that? How do I fix it?

25

I’m still thinking that is an Asterisk error…

Any idea?

26

Bad checksum is either an artifact of running your packet logger on the source machine, or indicates hardware problems.

If this were fundamentally an Asterisk problem, lots of people would be reporting it.

27

Yes, you’re right, but I don’t know what else think…

I really have to make it work.
