[solved] freepbx with lancom router

General Help
1

hi there,

i want to use freepbx in combination with my lancom 1823 voip router. the router is connected via isdn to the cable network. i want to configure freepbx so that it uses the two isdn channels for outgoing/incoming calls. furthermore, i want to use additional voip trunks configured at feepbx for outgoing calls.

lancom offers a tutorial (unfortuneately in german, but the asterisk syntax shall be understandable) http://www2.lancom.de/kb.nsf/b8f10fe5665f950dc125726c00589d94/e1759294d6f0c6e0c12573e60050acb4?OpenDocument

now my questions:

  • freepbx uses mysql instead of the config files. where can i setup all the settings, e.g. extensions.conf?

  • i have created a user to connect freepbx with lancom router. the outbound route of freepbx doesn’t work, i always get a line is busy signal. a trace of the call is attached.

if i put the user 44 credentials in a sip phone, it works -> config on lancom side seems to work.

Any suggestions why i cannot make an outgoing call from a phone logged in at the freepbx using the lancom outgoing route?

first of all thangs for the answers
i have managed now the setup a step further. I can make internal calls and external calls via the voip trunk. but i am not able to answer incoming calls (busy sign for the caller) or outgoing calls via the lancom router (isdn). i get always a line busy signal.

accoring to lancom support, the router cannot handle trunks. thus, how can i setup the following?
exten => _X.,n,Dial(SIP/${EXTEN}@192.168.10.1|40|r)
$exten should be the sip user connecting the lancom and the freepbx.

thanks for the help!

I have not set up any VOIP’s yet.

I recommend this reading.

And this Forum is another good one:

Hope that helps

I can only answer this question:

  • freepbx uses mysql instead of the config files. where can i setup all the settings, e.g. extensions.conf?

Once you have set the IP address on your FreePBX server, you put that in your browser (from a PC on the same network of course).

Then click on Admin in the lower left and then FreePBX Administration.

And when that comes up you will see Extensions, etc. under the Setup tab.

Am I off base?

hello tadpole,

thanks for the reply. i have found the setup, of course, but i do not find in the general settings some of the features listed in the sip.conf, e.g.
[general]
port = 5060
bindaddr = 0.0.0.0
context = sonstige
allowguest=yes
srvlookup=yes
canreinvite=no
language=en

and where can i realize this what should be in the extensions.conf?
[my-phones]
exten => 300,1,Dial(SIP/300)

exten => _20X,1,Dial(SIP/${EXTEN})

exten => _X.,1,Verbose(2,Dialing to User ${EXTEN} on Lancom)
exten => _X.,n,Dial(SIP/${EXTEN}@192.168.10.1|40|r)
exten => _X.,n,Verbose(2,${DIALSTATUS})
exten => _X.,n,Hangup

port = 5060 is set in the Extensions. I believe that it does not ask initially, being that 5060 is the default, but when you edit a SIP Extension it shows it.

context and canreinvite are Extension settings also.

Language is setup in the Language tab.

Most of the rest is under the Tools tab and then Asterisk SIP Settings menu.

As for what should be in Extensions, etc. … I learned a lot from this doc:
PBX in a Flash® without Tears: http://dumbme.mbit.com.au/PiaF/PiaF_without_tears.pdf

I am writing my own guide to a specific system, too… It might help:

The info you have is for Asterisk without FreePBX. FreePBX does most of the work for you.

The extensions are built by FreePBX for the dial plan. You should be able to make the device work simply be setting up a trunk to it.

The context they used is only for an example. FreePBX has it’s own context’s IE: from-internal, from-pstn etc.

ok, i have finally managed it to get everything working. the required options are sometimes hard to find, but now it works.

thanks for all answers!
