TRANSFERRED INBOUND CALLS FROM HP4K to OSBIZ X8 : BLOCKED/CANNOT TRANSFER

TRANSFERRED INBOUND CALLS FROM HP4K to OSBIZ X8 : BLOCKED/CANNOT TRANSFER

TRANSFERRED INBOUND CALLS FROM HP4K to OSBIZ X8 : BLOCKED/CANNOT TRANSFER

(OP)
Hello Gents,

I was simulating the inbound calls from our setup of HP4k (tie trunks) to OSBIZ x8 via QSIG format. Btw, all the extensions from the setup are IP.

Here's the scenario of our inbound calls:

Dialing the the PILOT NUMBER > AA-XPRESSIONS will answer > We will press "0" or any extension number to the HP4K > Then from HP4kK extension we will transfer the call to OSBIZ X8 > Transfer failed. The calling party will be recalled again on the extension who transferred the call.

But, if the scenario is like this:

Dialing the PILOT NUMBER > AA-XPRESSION will answer > We will direct dial the extension from OSBIZ X8 > Inbound calls is successful

Here's my cot, cop and zand for your reference:

RE: TRANSFERRED INBOUND CALLS FROM HP4K to OSBIZ X8 : BLOCKED/CANNOT TRANSFER

Hi.

First check if TTT is added in COSSU/COS of the trunks.
Also check NOCT (No notification for call transfer and call hold supplementary services) in COT of OsBiz - 4k trunk.
- If you do not want to send transfer messages to a specific trunk then NOCT needs to be set in the relevant COT of that trunk or route.

And eventually NOCI (No notification for conference suppl. service) .

If still not working, check in HISTA:
F5417 - mandatory missing info elem - L3 err message

If you are familiar with RMX trace, set up a trace with :
CHA-DIAGS:COMP=CP2,S04=ON;
S04 - Document unsuccessful call transfers within the CP trace
In the trace (via Message doctor tool) you should see "transfer failed" message cause.

Hello @adibv

It seems that the issue is on our CO - PRI TRUNKS of HP4k. Because we try to simulate an inbound and externally transfer the call to Mobile or Home number for example.
Same issue is being experienced. The call is returnung back to the phone and shows "CALL WAITING"..

External Transfer is possible on our Hipath 3000/Osbiz Systems. So technically we are just missing a parameter on our CO - PRI of our HP4k. Either Cot, Cop or COSSU.

If you have any info. Please it would be our pleasure :)

Hi.

Without a Trace and Hista, analysis is hard to make
Still, a standard CO trunk should have:

Still paramaters may be different depending on Provider.
Any additional paramaters especially in COT may lead to issues.

Just follow the previous hints with/without NOCT,NOCI param. in COT.
And also with DSDL param. in COT.

RE: TRANSFERRED INBOUND CALLS FROM HP4K to OSBIZ X8 : BLOCKED/CANNOT TRANSFER

OS4K does not like mismatched node number formats when transferring across trunks. By that I mean single level (node 100) or triple level (node 1-1-100).

Check your TDCSU and RICHT for configured node numbers, make sure they are not missing, and they match the level of node number configured in ZAND ALLDATA and KNDEF.

If not sure, post the output here.

DSDL is nothing to do with transfers, it's not relevant in this scenario. It prevents divert infos appearing in the setup. We are not diverting anything here.
