Asterisk Setup for Community VoIP

Thanks Ian, that's what I did.

Using the #81. prefix I noticed in the Asterisk debug file that the softphone (I use SJPhone but I also think it was the same with the Xten I tried) or Asterisk seemed to be replacing the # witha 3 digit numerical code for #(I think but did not keep a note of it) or something and sending this string to Asterisk. So stripping off the first 3 characters of the string gave a different number to the one I thought I was passing to Asterisk which led to a 404 error. Does that make sense?

I was just curious as to why my Asterisk setup was receiving a numeric code for # rather than the # symbol itself and whether that was a config issue in Asterisk or something to do with my set up.

If other noobies follow the original code with #81 they may well have the same problem as me and give up. It might be a good idea to replace the #81 in the original guide with a pure numerical prefix.

I would find it strange if I am the first person to to come across this problem.

Cheers

Hi Tony

I have just edited an extensions.conf file to start with #6 for voipuser and it works fine from my deskphone and x-lite. I would have a look in the features.conf and see if anything is in there. What version of * are you using ?

Ian

The three figure code wouldn't be 035 would it? (# in ASCII)

Check that your keyboard is set up correctly and you haven't got anything remapping the keys.

Hi, I've rerun again with _8 and _#8 as dial prefixes and appropriate strip setups, the former works and the latter gives a 404 error and I get the following SJPhone log snippets (phone no replaced with number):

At some point in the handshaking process the # gets changed into %23 (hexadecimal ascii code for #). My gut feeling is that this is neither a SJPhone or local machine issue but at the asterisk server end as I had similar problems with X ten on another local network machine.

I've also tried stripping 1-7 characters from the _#8. number all result in 404 errors. which probably suggest that the % is not allowed.

For information I am using the Xorcom distribution with new sip.conf and extensions.conf files.

TonyB

Hi Tony.

Ok This isnt an Asterisk bug in its self, Xorcom does use macros similar to AAH, This must be in the macro that this is happening as I have tested it on * and dont get any errors. I will be doing some testing on my lab system that is based on xorcom so I can see if it is a script problem. Personally startin a dial string with a hash is not good practice as # is the standard end of dial string for telecoms networks.

Ian

Thanks Ian. I don't think it is one of the Xorcom macros as essentially I've replaced the sip and extensions conf files with new simple conf files to help me learn Asterisk, so it shouldn't be calling any macros from within those files. Maybe there is conf file elsewhere in the Xorcom distribution that I need to check.

I used the Xorcom distribution because I am very much a Linux beginner (slightly better than newbie ) and the distribution seems ok for me with a menu driven linux frontend that helps. Having said that I do get a couple of error notifications. Are you a Xorcom expert? Which forum would you suggest I post the queries to? I also have a query on SJPhone also.

Thanks to the forum, I now have a working Voip User connection and am looking to extend that to Sipgate and beyond.

Thanks again for your help.

TonyB

Hi Tony

I have tried the #8 on my xorcom box and its fine with it using xlite, As I mentioned using a # may not be a good idea, and my reservation was well founded as you cant dial a number starting with a # from a Budgetone.

But here is the sip debug and its all aok

Well post your errors here, I do at the moment have 2 xorcom boxes in the lab as well as the live vanilla one. I wont claim to be an expert (But then again I dont claim to be an expert in anything) but xorcom is so close to vanilla * debuging it is simple. as to sjphone post it in the sip software forum Im sure someone will help.
BTW xorcom do have a forum but when I posted a query I had with ISDN and TDM400 cards mixed I never got any help
But then again its a bit of an odd build with multiple isdn2 cards and a tdm400 for fxo.

Hi Dean

I'm trying to configure my Asterisk box for outbound calls.
I'm callin a friend in the UK.
Below you can see what I've got. Any idea?

First trial +44(798)470-xxxx :
-- Executing Dial("SIP/200200-2f24", "SIP/44798470xxxx@voipuser||Ttr") in new stack
-- Called 447984700318@voipuser
-- Got SIP response 404 "Not found" back from 83.143.18.16
-- SIP/voipuser-4780 is circuit-busy

Second trial +44(0798)470-xxxx :
-- Executing Dial("SIP/200200-13f9", "SIP/440798470xxxx@voipuser||Ttr") in new stack
-- Called 4407984700318@voipuser
-- Got SIP response 404 "Not found" back from 83.143.18.16
-- SIP/voipuser-e3c7 is circuit-busy

sip.conf

type=friend

Thanks!

Fernando Gomes

Hi

You have two problems,

1. Your trying to call a mobile which wont work.
2. The dial string is just the UK number with no 44 so for example to call a london number it would be 0201231223 not 442021231223

Hope that helps Ian

Hi there,

I have compiled and installed the latest version of the asterisk server
on a Linux(centos) box. I am now trying to configure outgoing dialing using
a voipuser account. Unfortunately after trying out the procedure described
on the webpage :
"asterisk support for community VoIp) at : http://www.voipuser.org/forum_topic_330.html

but I am unfortunately unable to make outgoing calls. I get a
call failed (user not found) error. I am using the latest version of
XTEN lite as my SIP client. My Aterisk installation otherwise
works and I have verified this by calling from one XTEN
phone to the other XTEN client successfully.

I have also independently configured XTEN to use my voipuser account
information directly and I was able to successfully call a phone
number in the US.

I am copying below the additions to sip.conf and extensions.conf
(changed IP address to 100.200.300.x , username etc). These machines
are not behind a NAT and directly connected to the internet. I am
also attaching below the SIP messages by turning on "sip debug" in
the CLI console of Asterisk.

Any help would be appreciated !
thanks
Yuvraj
