Welltech Billing 6600

by Joe Mwigz on Monday 11 of February, 2008 [09:00:14 UTC]
Hi there.
Anybody using WellBilling 6600 from Welltech? I upgraded mine to the new farmware version but having problems comitting any new changes to the database!
From Apply Change Report-->Update Status all changes are stated as "Wait to be applied". I have hit "Apply changes" 100times, Soft Reset system, rebooted, and nothing is working.
Any idea?
Thanks

I also happen to stumble a generic welltech unit. I am using Trixbox, but my 'status' light on the welltech unit keeps blinking (unable to register proxy, right?) so what could be cousing this? any one have any idea?
thanks

Re: Generic-looking unit:

I managed to succesfully register all the lines from my fxo-4 wellgate into asterisk, then I can place and receive calls(setting the hot line function to an asterisk extension)... but...
The problem arises when I try to place two simultaneous, inbound or outbound calls, for some reason asterisk is mixing the channels and half hanging one. Sometimes my asterisk box is crashing after.
Settings in the wellgate:
Mode = Proxy
Detect silence = no (setting only available through telnet connection)
Echo canceller= yes
codec = ulaw
dtmf = inband
routes = From ip to FXO ---- From FXO to IP

In asterisk:
add peers for every line (put an x in line number in the wellgate if you don't want the to register this line)
fxolinenumber
type=friend
username=fxolinenumber
secret=somesecret
host=dynamic
nat=no
canreinvite=no
context=line1
disallow=all
allow=ulaw
dtmfmode=inband

Extensions.conf
;this is for receiving calls
line1
exten => 901,hint,SIP/joe&SIP/silv&SIP/joe_office ; Channel hints for presence
exten => 901,1,answer
exten => 901,2,wait,1
exten => 901,3,PlayBack(Thankyouktob)
exten => 901,4,NoOp(${CALLERID})
exten => 901,5,Dial(${HINT},30)
exten => 901,6,Playback(vm-nobodyavail)
exten => 901,7,Playback(vm-intro)
exten => 901,8,voicemail(s500)
exten => 901,106,Playback(vm-nobodyavail)
exten => 901,107,Playback(vm-intro)
exten => 901,108,voicemail(s500)
exten => 901,109,Hangup()
line2
same as above but replacing the extension for 902

With this configuration if an extension is busy and a second call enters, to the available fxo port, all my phones ring ok, but if I answer any of them, the channels are bridged and the mess starts.
With outbound calls the behavior is similar, if I select line one by the command dial(SIP/linenumber1) I hear tone from the fxo and can place a call normally, but if try to connect to the second outbound line dial(SIP/linenumber2), it jumps to busy and half hangs the first line.


Hope this helps some one, and I will appreciate any tips about why my sip channels are bridging.


Generic-looking unit: "FXO-06"

by Marc Tompkins on Wednesday 26 of July, 2006 [16:15:40 UTC]
For my first-ever Asterisk setup quite recently, we bought an FXO gateway sight-unseen on eBay: "6 Ports FXO VOIP SIP PSTN Gateway Asterisk IP PBX". I have no idea what possessed us to plop down $350 on something with such a generic description, but it turned out OK: it's an unbranded Welltech WellGate 3806, and firmware/manuals/etc. downloaded from the Welltech website work just fine. We could have spent far more money and got far less.

However, I've still got some kinks to work out, so if anybody can give me some pointers I'd appreciate it:

- Registration: is it important? The lines all show as "Not Registered", even though my SIP and security settings seem to match up perfectly with Asterisk's. At one point, I went on a binge of wild experimentation - I still don't know exactly what-all I tried - and I got the lines to show as Registered, but then my incoming calls got transferred stright to limbo. Didn't ring on any extension, never went to voicemail, nothing. So I went back to my previously-tested config - what I have now, where the security settings look right, but the lines still don't register - and at least the phones ring!

- Possibly related to registration: CallerID. What shows up on the extensions' displays is our own line numbers, not the caller's number - in other words, if our line 2 is "555-1235", and we receive a call from 213-822-3313, what I want to show up on our ringing extensions is 213-822-3313. Instead, our own number shows up. I suspect this is because the FXO port looks to Asterisk like an external phone, probably because we're not registered ahead of time. Any ideas?

- Half-dropped calls: intermittently, incoming calls will appear to be silent. The caller can hear us, but we can't hear them. There are lots of variables between the FXO and our extensions, so I'm not asking for detailed diagnosis, just some suggestions for places/things to look at.
    Our setup:  
      6-port Welltech         =>   Trixbox 1.1       => 6xGrandstream GXP-2000 
      (3 lines connected)           AthlonXP2200         hardphones
                                                    
Thanks! If I find out anything, I'll add it to this thread.
