remote login

[umop3plsdn]

So for the first time we are having people connect in to our dialers outside of the LAN. I had to obviously create port forwarding rules in our firewall to accomodate this. Also, add some entries in the sip.conf to allow outside connections
externip=X.X.X.X
localnet=192.168.1.154/255.255.255.0
nat=yes

Now the remote location can register one xlite just fine. But when it comes to the second since they are coming from the same ip address because they are behind a network themselves. I'm sure many of you probably do this already. Just wondering what else I have to do to basically tunnel each xlite session to the unique station.

[williamconley]

Use Zoiper instead. It speaks "IAX" and then you don't have to fight this battle.

Technically SIP cannot perform this miracle (it is impossible for the SIP Protocol to survive a double NAT scenario ...). That being said, thanks to packages like Vonage and many others, it is possible to configure your router to "fix" the situation with a sip algorithm. However: That can be problematic and specific to the router in question. Generally easier to put your Vicidial on an external IP (as long as you lock it down this is actually an improvement in your Vicidial communications). If you do this by adding a 2nd NIC to your Vicidial server, this will not change your local interaction with Vicidial at all.

And to nip the question in the bud: No, changing to IAX for a couple soft phones does NOT mean you have to change anything else to IAX. Not related to your trunks/carriers or internal phones. You can add as many IAX/SIP phones and IAX/SIP trunks and mix them any way you like, Asterisk will figure it all out when they speak to each other.

But your IAX phones will need to connect to IAX accounts under Admin->Phones (in the dropdown, it will need to say "IAX" instead of "SIP").

So: Either change these external phones to IAX or get another IP for your Vicidial server and be sure to lock it down with iptables (whitelist access only). Take your pick

Oh:

when you post, please post your entire configuration including (but not limited to) your installation method and vicidial version with build.

this IS a requirement for posting along with reading the stickies (at the top of each forum) and the manager's manual (available on EFLO.net, both free and paid versions)

You should also post: Asterisk version, telephony hardware (model number is helpful here), cluster information if you have one, and whether any other software is installed in the box. If your installation method is "from scratch" you must post your operating system and should also post the .iso version from which you installed your original operating system. If your installation is "Hosted" list the site name of the host.

If this is a "Cloud" or "Virtual" server, please note the technology involved along with the version of that techology (ie: VMware Server Version 2.0.2). If it is not, merely stating the Motherboard model # and CPU would be helpful.

Similar to This:

Vicibox X.X from .iso | Vicidial X.X.X-XXX Build XXXXXX-XXXX | Asterisk X.X.X | Single Server | No Digium/Sangoma Hardware | No Extra Software After Installation | Intel DG35EC | Core2Quad Q6600

[umop3plsdn]

Wow thank you SO much for your help! You are about to save a lot of time and stress. I setup an IAX extension in iax.conf and created the phone in vicidial. Zoiper registers just fine i can also place manual dials from within zoiper. However, anytime I try to login to a campaign it doesn't dial in to me at all. What else am I missing?

[umop3plsdn]

Oh and i'm using Vicidialnow VERSION: 2.0.4-121 BUILD: 80424-0442. I will be upgrading soon but it has a TON of custom work in it that i'm going to have to adapt later. Also, i've purchased the manual several times years ago which was brilliant i'm actually thumbing through an older copy for 2.0.2 now trying to get a smidgen of help to get this IAX extension to ring in to me

[umop3plsdn]

Is there anything that needs to be added to extensions.conf to have iax clients connect to vicidial?

[williamconley]

iax connectioned are not managed in the dialplan. LOL

iax.conf

you may want to upgrade now to save yourself a lot of hassle.

Seriously consider a fresh installation of Vicibox 4.0 from the vicibox site. You may find that your "ton of custom work" is now redundant from all the stuff that was added between 2.0.4 and 2.6 (trunk) presently in operation. SIP and IAX configuration is now handled directly by Vicidial. No configuration file editing is required.

[umop3plsdn]

I definitely don't have the option of upgrading right now and I gotta get these remote agents on today. I'm definitely going to setup a new box though to eliminate these frustrations for the future. But for all intensive purposes what would cause it not to ring the extension when going through the login screen? It's basically acting like I had changed the ip address and didn't run the update_ip script. Although it's definitely not that since i'm just adding an IAX client. Here's what I have in my IAX.conf everything registers fine and I can make outbound calls within the application just fine just not throught vicidial.
[remote01]
type=friend
accountcode=remote01
context=default
auth=plaintext
host=dynamic
secret=test
disallow=all
allow=gsm
qualify=yes

I also had added the phone under admin phones and made sure that the protocol was IAX2 and that it mirrored the configuration of the sip phones minus the client protocol. Is there anything else i'm missing here to get this working? I obviously reloaded and restarted the server after adding everything as well. Also, this is all currently on the LAN till I can get it working here first

[williamconley]

Ya lost me.

If the phone "registers", then you test an agent login. If the agent's phone rings when the log in, they answer and hear "You are the only person ...". At this point, they are an agent on the system and logged in ... and when they "make calls" it is not related to their phone in any way and works as if they were in the building.

IF, on the other hand, the agent login does not make the iax phone ring ... you're not actually registered. Open the port. .... otherwise, describe the problem in a bit more detail ("everything registers fine and I can make outbound calls within the application just fine just not throught vicidial." is not entirely descriptive).

[umop3plsdn]

Sorry about not being that descriptive lol you'll have to forgive me I stayed up all night trying to resolve this issue of remotely logging in.

When I was saying the client was registered I was referring to within asterisk itself "Registered IAX2 'remote02' (AUTHENTICATED) at 192.168.1.254:4569" I was then able to use the dialpad in zoiper to dial my phone number with 9 for an outside line everything worked great. Also, there are no firewalls between me and the dialer at this point either.

The problem is when i'm going to login to a campaign for vicidial and the agent phone is not ringing so I don't get to hear "You are the only person in this conf".
Again, i'm sorry that i'm not clear haha just really tired. I understand its not normal for you helping someone with an older version such as myself so I appreciate you taking the time to help me. Also, if all becomes a success I would like to donate some money your way for your help.

[williamconley]

Ya lost me again. Are you saying you registered the asterisk server to zoiper or the zoiper phone to asterisk?

Zoiper being able to call out does not mean it is registered. For your zoiper phone to Receive a call, registration from Zoiper to Asterisk is required. This will cause the agents "iax2 show peers" account to show an IP address ...

Does the zoiper interface say it is registered?

[umop3plsdn]

Wow i'm on a roll here haha let me see:
my client is registering in asterisk fine

IAX show peers yields the following:
remote01 192.168.1.254 (D) 255.255.255.255 4569 OK (3 ms)

I can make calls just using the application zoiper itself just cant get it to call me when i try to login to vicidial i dont get the call launch to the agent saying you are the only person in this conference it doesnt even ring to the agent phone

[umop3plsdn]

ive even gone as far as creating an extension in extensions.conf to test that it will receive an incoming call with:
exten => 401,1,Dial(IAX2/remote01@remote01/s||t)
exten => 401,2,Hangup

I dialed extension 401 from an xlite and it rang in to zoiper fine so I know that the phone itself is definitely registered. I've also made sure that in admin vicidial under phones that remote01 is listed as a IAX phone

[williamconley]

in that case you need to check the asterisk cli and find out why it does not dial the agent (or why the call does not go through if it does dial the agent ...).

[umop3plsdn]

Hrm no errors showed up plus I didn't even see the attempt of it to ring the client:

I changed the phone numbers to conceal the number

[umop3plsdn]

the " Hungup 'IAX2/remote01-1' came after i clicked logout because it didn't call the client and went to the call agent again screen

[umop3plsdn]

But on the other hand I noticed it does the same thing when it rings an xlite i dont get any output on my screen. Until the case of xlite when i hit the pickup call button

[williamconley]

set verbose to a higher number (at least 4)

debug mode for iax2 and sip is handy, too.

If I don't have the softphone registered at the time I try to login it does behave differently and does:
== Parsing '/etc/asterisk/manager.conf': Found
== Manager 'sendcron' logged on from 127.0.0.1
Dec 5 14:37:37 NOTICE[10552]: channel.c:2514 __ast_request_and_dial: Unable to request channel IAX2/remote01
== Manager 'sendcron' logged off from 127.0.0.1

So i'm thinking that it does actually see it. It's strange that it just wont ring.

[williamconley]

and yet you have no actual generic command line output, only debug output. what is your verbose set to and how did you start up the console?

[umop3plsdn]

For that output I had connected to the asterisk console via asterisk -r and then
atlantis*CLI> set debug 7
Core debug is at least 7
atlantis*CLI> iax2 debug
IAX2 Debugging Enabled

Then i tried to login and collected the output and pasted it to this thread

[williamconley]

perhaps your /etc/asterisk/logger.conf has been modified?

[umop3plsdn]

Really hope you aren't getting annoyed with me i'd feel terrible. I really appreciate everything you have gone over with me so far. Here is the output of logger.conf
[logfiles]
console => notice,warning,error
messages => notice,warning,error,debug,verbose

[umop3plsdn]

Something as easy as adding new phones even though they are iax to any version of vicidial should be simple as pie. I have no idea why on earth it just doesn't want to send out the call upon login to vicidial

[williamconley]

what is your verbose set to

I note that you told me what your "debug" was set to, but not your "verbose". LOL

and now that you've shown the logger.conf, it happens to NOT have "verbose" on the console line. So you wouldn't see any verbose output even if you set verbose to 200.

I think you'll be pleasantly surprised when you put that verbose setting back. And then smack the technician that took it out. Severely. No bacon treats for at least a week.

you're still only providing the debug information that happens at end end of the call. something happened before that which logically caused the system to terminate the call. but we can't see what that was. we only see the car wrapped around the tree, I need the video from 30 seconds before the car was wrapped around the tree so I can see if a deer ran across the road or if the driver was texting a buddy.
