atcomsystems.ca/forum Forums TDM Business Telephone Systems Toshiba Telephones & Systems DK 280 rejecting inbound star service diverted calls on ISDN30 (PRI)

Hi,

We have a customer who has closed a few branches but has set up star service diversion on the office numbers to head office which happens to be a DK280 with a ISDN30 PRI circuit on BT. The 280 is rejecting these calls(something to do with an extra message in the call set up). We have tested this sevice to several other 280 PRI sites with mixed results - some work some don't!
My question is does anyone remember what is required to cure the problem? Is it an RPTU version change or 280 software issue or just a programming alteration?
Cheers
Rich

I would check the firmware version on the RPTU card first to make sure it is the latest.
What version software are you running on the DK280?
Did you do Digtrace? can you post it up here for us to look at?

All good questions bud.

I will first compare the software and firmware levels on the working and non working sites and post an update. I have not been to the main site as this fault has literally just landed on my desk

FYI,

I have upgraded the RPTU1 firmware from 1S to 2A which has made no change. (It was the easiest route to take first)
The 280 is currently running 5E software so I guess the next stage is to put it onto the lastest known good version (6N/P from memory?)
We have performed a temp fix by diverting the branches to a virtual number which then forwards to the 280 which accepts the call so we know that the problem lies with the ETSI message received from the network.

5E software on the DK280 should be fine.
2A on the RPTU is also the correct version to be using.

From memory I am not sure the DK280 supported the Information Element (IE message) which is what you are sending by trying to do with the * diversion.

Pretty sure we have had to use a call forward external to get the calls to the external destination.
Exchange based diversion only worked on PSTN lines not the BRI or PRI.

Strange that you have got it to work on some other sites, are they running a PRI supplied by someone other than BT?

No mate they are all on BT although different exchanges. I will visit the known working site in the near future and check the config and confirm software/firmware versions.
