Cannot make international calls

[cjtucker1976]

we occasionally have this issue and we are a non-profit and get hit with a pretty hefty service call when this happens- but it happens so often so any how- to help would be appreciated.

We cannot make any international calls- get a fast busy. The last time it happened the tech said he "assigned DMI 17 to insert 011 on international calls to RLI 17 " Any help on how could check this? what module to check? I called out carrier and they said to contact pbx vendor.

LD 86
REQ prt
CUST 0
TYPE rlb
RLI 17

look at the output from what you have said you will see DMI 17 assigned

same load
REQ prt
CUST 0
TYPE dgt
DMI 17

here you should see
DEL 0 (delete no leading digits)
INST 011
CTYP xxxx (This would be NCHG=no change to type of number (TON), UKWN= TON Unknown, or INTL= TON International)

If you are inserting the 011 I would expect it to be UKWN, usually when you have TON International the carrier doesn't require the 011 (but this is not always the case).

Another thing you can do is in LD 96
. stat dch
. enl msgi x (enable inbound messaging against the D-Channel (add all the numbers seen on the previous STAT))
. enl msgo x (enable outbound messaging against the DCH's)
. enl mon tty (enable the output of the messages to display on your terminal)

make the call and you should see the outbound SETUP message and also reason for failure coming back in. You can post results back in here if you need help interpreting

Also, look for the FRL assigned in Step 1 of bignose21's instructions.

Then go to LD 87 and

REQ prt
CUST 0
TYPE nctl
NRNG 0 7

Typically the NCOS and FRL will match but review printout to double check.
If FRL from Step 1 was 5 - check to see what NCOS it matches.

Then, print out your telephone and make sure that the NCOS assigned is equal to or lower than 5 (or whatever was assigned in Step 1)

You could if you wanted use this tool

and find out how all your numbers are dialed and what routes are selected.

***Should be equal to or greater than 5****

[jaxuser]

what NCOS is your phone?

 

[cjtucker1976]

NCOS 6

I also tried from other phones that are set to NCOS 6 and still get fast busy

 

[bignose21]

Its not NCOS as you wouldn't have seen the outbound setup message if there was any barring in effect.

Did you enable MSGI and MSGO on DCH 2 as you only posted the outgoing (MSGO) messages.

LD 96
STAT MON

if the fail is incoming from the carrier something like "Invalid number format" it might be the carrier is not liking the TON International mixed with you also sending the 011.

So i guess you dial 901144xxxx is 9 the ac1
Ld 86
Req prt
Cust 0
Type esn

If it is
Ld 90
Req prt
Cust 0
Feat net
Tran ac1
Type all

Find the match closest to your numer less the ac1 so may just be 011 as spn etc.
Confirm the RLI that is associated with that number.

If it is 17 as you think as a test try removing the 011 from your DMI

I've rang the UK number OK over this side of the pond using (0)1926499555.

Therefore you need to follow the steps from the beginning as we have been trying to help you solve the problem.

I'm assuming that you dial from the phone an access code such as "9"?. If so, then the full number from the phone would probably be
9011441926499555
We in the UK use "00" for international calls, but it's usually "011" in NA. The Meridian phone system will most likely be using a SPN of 011 and this will be found in LD 90.

Something like this below.

>LD 90
REQ PRT
CUST 0
FEAT NET
TRAN AC1
TYPE SPN

SPN

SPN 011
FLEN 16
ITOH NO
RLI 1
SDRR NONE
ITEI NONE

If that doesn't work, then just press "enter" at the SPN prompt to print out all the SPN's in case "0" or "01" is used.

Then follow the steps in LD 86 by printing out the RDB and DGT to find out if any conversion is done.

Personally, I'd print off all your networking information as suggested in my first reply so that you can find out the whole picture of waht is dialled.

My international calls use DMI 0, not sure why you need to insert the 011, is the user not dialing 011?

Thanks,

BTW in the original post you mentioned that the tech added 011 to the DMI as it was not going to PRI. This is usually the prompts at the bottom of the NET_DATA say INTL set to 011 would mean that if the call has a TON of international the 011 is removed from the call. So in affect the tech has added the 011 making the call 01101144xxxxxx then the NET_DATA removes 011 leaving 01144xxxxx. If the carrier does not accept 44xxxxxxx TON INTL then you would be better removing the 011 from the NET_DATA.

But for now as Firebird says you would be best served establishing the routing of the call and make sure you are looking at the right bits. The normal format to pass a number would be:

44xxxxxx TON INTL
01144xxxxx TON UKWN
