SBO (Branch Office) NCOS Barring Problem 2

[sl1input]

I have vaious Rel 4 Survivalble Branch Office (SBO) Sites connected to a Rel 4 CS1000m, all sites have Sig Servers and Virtual Trunking.

The SBO sets register to the Main Office (MO) and use all the MO facilites. To make PSTN calls the SBO phones dial out from their local lines, using a Virtual Trunk to get back for PSTN access.

The problem is that the SBO phone ignores the NCOS programmed on the i2001 or i2004 and with NCOS 1 or 2 can dial mobile/cell phone and full PSTN access.

If i create a local digital set e.g. 3904 to the SBO the set <<DOES>> follow the NCOS tables and at NCOS 1 is internal only.

So i guess the fault is with the Virtual Trunks not programmed correctly???

Here's the Virtual Route:>

Looking at the FRL's, this may be the problem???

But im not well up on FRL feature at all.

Help much App.

Is this route at BO or MO?

FRL in the route is a mapping for NCOS: FRL 5 is map to NCOS 0.
This may be the problem. However, the rout is ESN5 meaning you are sending NCOS through the trunk (Travelling NCOS=TCOS)

Give a try changing FRL
I may give you an example that is working

 

[telecomnorth]

using a Virtual Trunk to get back for PSTN access" is the issue.

When the call routes back to the SBO it uses the NCOS of the SBO virtual trunk (ld 14) and not the NCOS of the phone. Restricting remote office IP phones has to be handled in the Home PBX.

Unless there is a way to have traveling NCOS values on calls between PBXs. Does anyone out there know if this can be done?

The FRL in the RDB (ld 16) come into play on direct trunk access (code restrictions) so they shouldn't be the issue here.

dlesap: Can you provide setup details on Traveling NCOS. Is it a simple setup?

To identify NCOS travelling through ESN5 trunk you will see 3 front digits added to your number when monitoring the DCH:
dialing 1234 ---> 1051234 in the DCH for NCOS 5 set

Thanks guys.

The Virt Rt was from the BO switch, i will get Virt Trunk prints from both MO & BO when possible.

I will also setup up some DCH monotoring to see if NCOS is being sent/received.

Scenario: IP Set at BO regist'd to MO

Q: At the MO i should see the NCOS being sent out?

Q: At the BO i should see the NCOS being received?

Q: dlesap: Your route is SIGO:STD, mine is ESN5, i thought STD would not send the NCOS over the route????

 

[dlesap]

Q: At the MO i should see the NCOS being sent out?
Yes cause ESN5 in RDB. Then you may see 10x+dialled digits

Q: At the BO i should see the NCOS being received?
Guess no, cause going through LD 90 of Main office. Not sure.
You may only have digits to be dialled out to PSTN.

Q: dlesap: Your route is SIGO:STD, mine is ESN5, i thought STD would not send the NCOS over the route????
That's right. I think it's not necessary to send it cause your phone is registered on the Main office. MO controls the restriction, not BO
