[asterisk-users] Doing asteriksk with a sip trunk

Mamadou NGOM Thu, 31 Mar 2016 08:25:07 -0700

Hello !

I ask if it is necessary to install DAHDI and LIBPRI if we want to connect our asterisk to an operator SIP (trunk SIP).

Someone for helping me.

thanks !!!

Did you notice this ............................^^^^^ value???
Yes, I did. But I assumed (hmm) that this was caused because this server is
not IPv6-enabled. See also here: http://stackoverflow.com/a/30703716/3172389
Should not be a problem since you are complaining abou TX packets, not RX,
but...

does dmesg say anything about this?
Nope, nothing at all.

But what I can do is set the interface into promiscuous mode with tcpdump,
then there should be no dropped packets at all, I think. I'll check to make
sure.

Thanks for the heads up, and thanks for thinking with me everyone!

Cheers,

Roel

I was thinking maybe there's a problem with the transmit queue, but 1000 is
the default value for txqueuelen and I have never needed to change it.

I have the default queueing discipline:

root@communiceer:~# tc qdisc show dev eth1
qdisc pfifo_fast 0: root refcnt 2 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1
1
1 1 1

The output of ethtool also looks good:

root@communiceer:~# ethtool eth1
Settings for eth1:

And the nic stats also look good:

The tcpdump that you are running is on the Asterisk box or via port

It's on the asterisk box itself.

I've already replaced the network card - no change.

Thanks,

Subject: [asterisk-users] Lost outgoing SIP packets

Hi list!

I have a problem where SIP packets sent by Asterisk do not hit the
wire,

I don't know what could cause this.

I'm running Asterisk 1.8.28_cert5 with full SIP debug. At the same
time,

doing a tcpdump of the traffic on the network interface. I can see in
the
SIP
debug log that asterisk is sending packets. Most of the time, I can see
those packets in the tcpdump, as you would expect.
However, sometimes Asterisk sends a packet that *does not show up* in
the

up).

This causes Asterisk to log the peer it was sending packets to

There is no outgoing firewall on this box.

Could anyone give me some pointers where to look?

If Asterisk logs "VERBOSE[13019] chan_sip.c: Reliably Transmitting
(NAT)

right? What could cause this not to be so? Are there network
statistics I

sending packets? Anything?

If more information is necessary please do let me know.

Thanks a lot in advance,

Roel
