Problems with Panasonic KX-TDA30 unable to dial out

[LesD]

I have a Panasonic KX-TDA30 switchboard which I will phase out once the PIAF system is fully functional. For the moment I have connected the 3 analogue line ports on the TDA30 to 3 OpenVox FXS ports.

Incoming calls are fine. However, outgoing calls from the Panasonic system phones are failing as the numbers sent seem to get corrupted.

Plugging a simple POTS phone into an PXS port works fine for outgoing calls, but the CDR is showing various corruptions of the number coming from the Panasonic phones.

Some examples: Each pair shows what was dialled and what the CDR shows:

902088027xxx
90208807xxx

902012345678
9020145678

9020xx095033
900xx0950

9020xx095033
9020xx0950

The errors are reasonably consistent but not absolutely so.

Any ideas as to where I go from here?

(I had an idea to try pulse dialling - can the OpenVox module deal with that?)

Just a thought... Have you verified impedance matches between each system? Impedance mismatch can cause problems ranging from echo to DTMF recognition problems.

Typically, most cards and systems I've seen default to 600 ohms. However, it is worth having a look at if you haven't done so already.

 

[LesD]

Randy, that sounds well worth trying. How do I go about changing experimenting with the settings?

 

[randy7376]

I'm unfamiliar with the Panasonic unit. Do you have an administrator's guide for it?

Looking at one of your other posts, am I correct in presuming you're in the UK?

My thoughts on this when I saw that were that your Panasonic unit is probably configured for interfacing with British Telecom while your OpenVox card is probably defaulted to US specs, unless you've changed that via the opermode option.

Not being familiar with OpenVox, do you know which driver your card uses? Specifically, which card do you have? It wasn't mentioned earlier in this thread.

It's been some 21 years since I've worked around any BT lines. Do you still have to have a master socket to wire off of if you want another extension?

Anyway, if you can follow-up on any of the above, it would be helpful.

EDIT: Found a "user manual" which appears to be the admin's guide. I couldn't find any mention of being able to modify impedance. It also appears this is strictly a UK model so the impedance is probably fixed.

 

[LesD]

I have the admin program for configuring the Panasonic and the only thing that looked worth trying was DTMF width but that did not help. The impedance is probably a hardware jumper or maybe not even that as the unit would have been made/customised specifically for the UK market - correct deduction on your part.

Changing the OpenVox card sounds much more achievable.

As a complete novice to Asterisk etc. I have no idea how to find the driver being used. I am using Asterisk 1.4.21.2.

The card is, I believe an a400P with 4 ports (3*FXS + 1*FXO).

The card does work with a regular BT POTS phone but that might be just luck. So I am keen to learn how to play with the configuration (where is opermode to be found?)

(A master socket is the normal way things are done here. Not so much as a technical issue but to be able to isolate the wiring up to the master socket as BT responsibility and the rest as the householders)

 

[randy7376]

My fault for not asking sooner, but, could you post the output of status, as well.

 

[LesD]

Where do I get 'status' from? All I can think of is FreePBX System Status which does not look too relevant.

 

[rossiv]

Open up a SSH session to the PIAF server or go to the console. Log in and after on the left you see "root@pbx:" or something like that, type "status". Copy and paste that here.

I have been looking around at some of the config files and copy below the contents of

zapata.conf
zapata-channels.conf
modprobe.conf

as it may show up something to experienced eyes.

(I spotted one thing which I wonder if it is the cause of an other problem: The Panasonic phones do not show caller ID on incoming calls.

Could it be the lines

callerid="Channel 2" <201>
callerid="Channel 3" <202>
callerid="Channel 4" <203>

instead of

callerid=asreceived

that may be causing that?)

LesD,

Since you're running Zaptel, I had to do a little digging to see if the same options exist in the Zaptel driver. It appears they do. According to the OpenVox wiki, the A400P uses the wctdm kernel module. It's been a while since I've dealt with Zaptel, so bear with me if some of the following doesn't seem to work.

While we're not modifying any configuration files at this point, it's still a good idea to have a back-up. This should be relatively safe to try.

1) At the console or via SSH, we want to stop Asterisk and Zaptel:

amportal stop
amportal kill
service zaptel stop

2) Next, you'll want to do the following:

lsmod | grep -i wctdm
lsmod | grep -i zaptel

Both of these command should not return anything. If they do, try to remove the modules manually:

rmmod zaptel
rmmod wctdm

3) We want to load the modules, manually with the following options:

modprobe zaptel 
modprobe wctdm opermode=UK fxshonormode=1

4) 5) Last thing to do:

 amportal start

See if your problem has disappeared, gotten worse, or has no change.

To put everything back the way it was:

 amportal stop
amportal kill
service zaptel stop
service zaptel start
amportal start

I spotted one thing which I wonder if it is the cause of an other problem: The Panasonic phones do not show caller ID on incoming calls.

My home system only has callerid=asreceived. It's worth a try. The only other thing to look at would be the cidsignalling= option. Not knowing anything about BT's CID, I did a little reading. Your settings seem to be appropriate assuming the Panasonic phones expect that type of signalling.

 

[LesD]

Thank you for all this effort.

I will try that in the evening so as not to disrupt calls.

 

[LesD]

Just tried that and the net result was all three fxs channels died. Reinstating as per your instructions resurrected them.

 

[randy7376]

Can you post the loaded kernel modules for me? The wctdm kernel module may not be the correct module.

lsmod

As an aside: You may have noticed in the end of my previous post the line:

You have new mail in /var/spool/mail/root

I have had a look at the file and it contains emails from the system.

1. How do I get these emails sent externally?
2. How do I view these email?
3. How do I delete them?

1. I believe you can do that in Webmin. Servers>Sendmail Mail Server>

2. Type 'mail' at the command line or through Webmin. Servers>Sendmail Mail Server>Read User Mail>root

3. Easiest way is through Webmin. Servers>Sendmail Mail Server>Read User Mail>root -- To delete all, hit the Delete All button at the bottom.

 

[LesD]

Rossiv: Your suggestion re sending mail externally:

I had a look at Sendmail and the only thing relevant looks like 'Domain Routing'. I put an entry there to route pbx.local to my domain but it did not work.

The routing screen does mention that routed domains must not be in the local domains list. Going there, it seems that pbx.local is hard-wired in for local delivery.

What I need to do is find where Asterisk and Linux the pbx.local domains are used.

 

[LesD]

Thank you. That has worked just fine for root.

Where do I put it for mail user: asterisk? (there is no /asterisk/ directory)

The documentation I looked at says:

"When delivering email to a user, sendmail checks to see if the user has a .forward file in his home directory."

What is the home directory for user asterisk?
