Asterisk Asterisk Support
1

I have been working on a new project, trying to get this Linux box with Asterisk running on it to connect to an external SIP server to make outgoing calls. As of right now I can make all the internal calls I want to any of my 5 extensions. I have called the external sip server “SWITCH” in sip.conf. I have provided my files below. I will be so greatful if anyone can help me call out to the outside world.

extensions.conf:
[general]
static=yes
writeprotect=yes
autofallthrough=yes
clearglobalvars=no
priorityjumping=no

[sip]

I think you’d want to change this:

to this:

or this

depending on how your provider wants the call.

Just noticed you have nat=yes in sip.conf on that peer without specifying localnet and externip in the general section. Those will need to be set. Do you also have the correct ports forwarded on your router and open on your firewalls? Can you ping the external host?

5

I don’t think it’s necessary that I declare this because all the IP addresses being dealt with are in fact the external IP addresses. This is on a college campus and all IP addresses on campus are accessible from outdside, in other words, they are not your average 192.168.0.x addresses

HI
with use of ur initial config plz send us ur Asterisl console logs when u make in out calls. plz send that cli logs

Since this is on a college campus, you may have simple firewall issues.

If the firewall isn’t open to allow traffic back through to your Asterisk box, you’re not going to be able to establish a sip session to an external provider.

What does sip show peers say? Are you registered with the switch?

Get that worked out first then work out how to talk to the chanel.

10

phone2/phone2 xx.xx.10.108 D N 2072 Unmonitored
phone1/phone1 xx.xx.10.107 D N 2051 Unmonitored
SWITCH xx.xx.7.98 N 5060 Unmonitored

11

This is what I now get when trying to make an outgoing call:

[Jan 3 20:55:32] NOTICE[11348]: chan_sip.c:2880 auto_congest: Auto-congesting SIP/SWITCH-08c91f38
[Jan 3 20:55:32] NOTICE[29274]: cdr.c:434 ast_cdr_free: CDR on channel ‘SIP/SWITCH-08c91f38’ not posted

12

Some one else on the list had the same issue. Run a SIP debug and see what happens. Also contact your carrier and see if they are receiving anything. Also some one else mentioned there may be a firewall issue.

13

In your sip.conf, in each of the blocks, stick a qualify=yes line in, and do a reload.

You may need to put a register line in sip.conf for the switch with your username and password.

You should see all of the sip devices showing up. If they are not showing up and registered, you will not be able to make calls.

Get the channel set up first. Once you are seeing the switch show up in the sip show peers, then work on talking to it.

14

Thank you to everyone who helped debug this issue… I have finally found the answer and figured I would share it with everyone. With the PSTN gateway registered in sip.conf as ‘SWITCH’, I simply call it in extensions.conf by:

‘exten => _9.,1,Dial(SIP/SWITCH/${EXTEN},60,tr)’

Now I have a one-way audio problem! :frowning: always something!

15

The one way audio is probably a NAT issue. Do you have externip= set in sip.conf ? Also you need to set localnet as well as forward the ports from your router to your asterisk box.

16

The thing with that though is that the Asterisk box is in a location on campus that it doesnt need the external or internal IP because they are the same. The whole campus has IP addresses that are accessible from outside networks. However, the phones that I’m using are behind NAT’s and they just simply have a 192.168.0.x IP.

17

I don’t fully understand your set up. Can you please draw a graph ?

18

The phones themselves are of campus. They are in different houses so they are behind their own NAT’s (in this case they are all behind netgear routers that need to be opened to deal with SIP and RTP). Basically if you open the right ports it works just fine with 2-way audio. Unfortunately, it can be a little tricky finding the right ports to open. Or I could just buy a router that accepts SIP and RTP.

19

How good are these routers ? I have found that the dumber they are the better. Port forwarding would not work well since you have multiple ports. If the issue is that the router’s are too good then for SIP (for Asterisk) you need to allow ports 5060, 10000-20000 UDP.
