Asterisk help

Hello all!

I'm a new asterisk user and for a while now I was using a couple of free VoIP providers for inbound and outbound testing. When I started working at another company, one of the perks was that I got a free VOIPo account.

My very first reaction was joy at thinking how cool it'd be to finally deploy my own VoIP gateway for the house. I have a Dell 1U rackmount server that I scored from Goodwill for $30 because it wouldn't post. (they weren't using ECC RAM.)

Well, I got the latest Trixbox/Asterisk/FreePBX ISO image and installed it and have run into a problem. Any VoIP device (softphone, Wifi-Phone, PAP2) can call out from the VOIPo trunk, but any attempt to call in gets a busy signal.

I have checked Google and scoured the Asterisk/FreePBX/Trixbox forums hoping to find a solution but have come up with bupkiss. In fact, some of the settings for the inbound calling, caused me to lose outbound call as well but I was able to get that fixed.

Here's where I need help. I need to find what I'm doing wrong and I hope I'm not the only person with VOIPo that has done this (much less pulled it off). I'm looking forward to getting this thing running and I have great plans for developing it from a testing box that I mess with on occasion to something that I can use full-time.

I have tried entering my credentials into a Zyxel P2000W (WiFi VOIP phone), X-lite for PC, and the PAP2, all work flawlessly both incoming and outgoing, so I know it's not a network issue.

Important information:
Inbound calls fail, but outbound calls work great only when through Asterisk server.
(Perfect quality, even on the old Zyxel Wifi phone.)
{VOIPo assigned #}=Ten digit phone number, no leading "1"
{VOIPo password}= VOIPO Assigned password.
I have "Allow Anonymous Inbound SIP Calls" set to "Yes" but setting it to "No" causes the same symptom and does not change the logfile output.

OS/Asterisk versions:
Asterisk version: Asterisk 1.4.22-3 RPM
CentOS release 5.3 (Final)



Inbound Route settings:
All default, except for the following items
- DID Number = {VOIPo assigned #}
- Destination - Ring Group 600 (all phones), (right now, only ext. 200 exists)

Trunk Settings:
(All fields not mentioned are using their default settings)
- Outbound Caller ID = {VOIPo assigned #}
- Maximum Channels =
- Dial Rules NXXNXXXXXX
- Trunk Name = VOIPo
===Outgoing Settings===
PEER Details:
host=central01.voipwelcome.com
username={VOIPo assigned #}
secret={VOIPo assigned password}
type=peer
context=from-trunk

===Incoming Settings===
USER Context = {VOIPo assigned #}
User Details:
secret={VOIPo password}
type=user
context=from-trunk
disallow=all
allow=ulaw
insecure=very


Registration String:
{VOIPo assigned #}:{VOIPo password}@central01.voipwelcome.com

When I get a call, this is the result of enabling SIP debug (level 10)


Here is a sample of the sip debug info:

I'll try anything, but while I do have the PAP2, I can't afford the digium card needed to bring a POTs line into the server. (theyre about $300!).

Thank you for your help!

put the DID on the end of your registration string like this:

user:secret@central01.voipwelcome.com/DID

Hello dswartz. I went ahead and tried your suggestion, and still a no-go. Same as above but still no incoming calls.

busy or fast busy?

Not to insult your intelligence, but I have to ask...

Let's say your Voipo number is 9195551234 and your assigned password is hg2y08x1.

Your register string should look like this:

9195551234:hg2y08x1@central01.voipwelcome.com/9195551234

You should have an inbound route that directs 9195551234 to a valid extension or ring group. (which it sounds like you already do)

Have you considered setting up a 'catchall' route to your desk phone? (Any DID/Any CID)

A friend of mine had a similar problem. He was trying to register to central01 and his DID was assigned to east.voipwelcome.com (east01, whatever the exact name is). I thought people could register to any of them (central, east, etc) but in his case, it made a difference.

Hello:

dswartz: There's about a 30sec pause of dead air (and I can see incoming SIP transactions from various IPs with the callerID info) then it cuts to a normal fast busy.

Fisamo:
I have tried it with the format described and without the /{DID} at the end. It did not appear to change things except without the DID at the end, I got "Ignoring this INVITE request". I have two inbound routes in place, one for anyDID/anyCID and one for the number assigned to me by VOIPo. Both of them have a target of Extension 200.

scott2020:
That might be the case, but what's really throwing me for a loop is that I plug my cred. into X-Lite or into my Wifi phone connected to the network (not through Asterisk) and both of them can send and receive calls without issue. Now an odd thing is that for the Zyxel wifi phone, I can't use hostnames so I have to use IP addressess, but I have never had a problem with its functionality.

Curiouser and curiouser...

Don't worry about insulting my intelligence, if you have something you want me to try, then by all means speak up. Chances are, you're thinking of something I'm missing or have easily overlooked.

Here is my config:

Outgoing:

trunkname voipo.com

username=user
fromuser=user
fromdomain=east01.voipwelcome.com
type=peer
secret=secret
qualify=yes
host=east01.voipwelcome.com
disallow=all
allow=ulaw
insecure=invite

Incoming:

User context: VOIPO_in

type=peer
secret=secret
qualify=yes
insecure=very
host=east01.voipwelcome.com
disallow=all
allow=ulaw
context=custom-voipo

p.s. I may be off base here, but I seem to recall having problems if I didn't use 'peer' for inbound.

Here's what I have

For Outgoing:

Code:

---

disallow=all
username=myDIDNumber
type=peer
secret=mypassword
qualify=yes
nat=yes
insecure=port,invite
host=central01.voipwelcome.com
fromuser=myDIDnumber
fromdomain=codeblue.voipo.com
context=from-sip
allow=ulaw

---

For incoming:

Code:

---

disallow=all
type=peer
secret=mySIPpassword
qualify=yes
nat=yes
insecure=port,invite
host=central01.voipwelcome.com
context=from-sip (this will be different possibly)
allow=ulaw

---

My register string is like yours, but with the / and DID after it.

I tried your config but I have never seen this context used. How did you define it?

scott2020:
I tried your config too and I don't know if I've taken a step forward or a step back. The line rings once, and then I get a male voice that says "The number or code that you have dialed is incorrect. Please check the number or code and try again."

I noticed that the log goes nuts when I call it, and it looks like the call IS hitting the server:

[Jun 17 16:10:18]


Another question is that I have the catchall route set to Extension 200 (softphone). Should I set this to Ring Group 600 (Ring all phones) or should I wait until I can confirm its operation first?

I can't thank you all enough for your help with this. I am very excited at the possibility of getting this up and running. :)

Here's something interesting. I looked in my vPanel to see what it was saying about registered devices. It shows: sip: (VOIPo phone number)@192.168.0.14

Shouldn't that be my WAN IP address? Is there anything in Asterisk I can use to adjust that so that it shows my IP? What are the ramifications of it using the .14 address (That is the IP of the trixbox server on my local network.

I can't give you asterisk advice, but as I recall, vPanel gave me an internal IP address when I didn't use STUN, but changed to my WAN IP address when I used STUN. The phone worked in both cases, and I was told this is normal behavior.

oh, sorry, that is something i put in extensions_custom.conf to massage CID and such. you can make it just what others have done instead. i think the internal IP address is suspicious.

Try your BYOD credentials, they're available in vPanel.
Navigate over to vPanel > Features > Preferences > "Softphone / BYOD".

Toggle your softphone status to On and hit Save. Use the credentials provided.

I see that menu too.
Did VOIPo change their mind again to continue BYOD?

Vpanel shows my external IP address.

In your sip.conf did you set your externip= or externhost= information? Also, my sip.conf has nat=yes in it. You also need to set the localnet=. If you are using PBX In a flash, trixbox, etc you might need to edit a custom config file since the standard ones get overwritten. I am running AstLinux so it is a basic Asterisk install.

Code:

---

externhost=fully qualified domain name of my outside IP
localnet=192.168.1.0/255.255.255.0
externrefresh=300
nat=yes

---

externhost can also be externip=xx.xx.xx.xx if you have a static IP.

Well, I am pleased to announce that the new sip credentials worked great! I was able to call out and receive a call.

The problem now, is that I was only able to receive ONE call. Now, I get the same "The number or code you dialed is invalid..." error on any inbound call. I have a feeling we're so close it's almost painful!

So here's what I have so far:

- I have an inbound route with any CID and any DID forwarded to X-200. (I haven't tried my "Ring All Extensions" yet..)
- X-200 and the WiFi phone can both call out till the cows come homw. This has remained unchanged.

- My registration string for the trunk is: (phone #): (BYOD password)@sip.voipwelcome.com/(phone #)
Note: There is no space between my BYOD password and the colon, just if I try to do so here, it shows up as a :(


My Outgoing Settings:
disallow=all
username=(Phone #)
type=peer
secret=(BYOD password)
qualify=yes
nat=yes
insecure=port,invite
host=sip.voipwelcome.com
fromuser=(Phone #)
fromdomain=sip.voipwelcome.com
context=from-sip
allow=ulaw

My Incoming settings:
disallow=all
type=peer
secret=(BYOD Password)
qualify=yes
nat=yes
insecure=port,invite
host=sip.voipwelcome.com
context=from-sip
allow=ulaw

What am I missing? Do I need to address the issue right now with the device registration from vPanel where it shows (phone #)@Local net IP address

Hello scott2020:

On your items described above, what do I do if the Asterisk server has two local networks? I've got a 192.168 network that's the "main" network and a 10.0 network for the VOIP phones, ATAs, etc..
Do I need two localnet directives?

Something else I've noticed too:

On the vPanel, when you enable the SIP/BYOD devices and you click SAVE, it changes the password!

Hi
You can put as many localnet= lines in the configuration as you need. Just put them one line at a time with the IP and subnet masks. I do that on my box at work because there are several local networks.
Scott

Ok, I give up.

I had VOIPo put a trace on my line and they said that they're getting a 404 when they send the call my way. I have scoured (yet again) for information about this error and about getting the server working but it's to no avail.

I appreciate everyone's effort in assisting me with this endeavor, but I've given up and I feel like I've bashed my head against this brick wall for three weeks. The one call I did receive was a false positive and I don't know why I can't get it to work.

Thank you, everyone.
