ISDN (PRI) orginated calls cannot transit to analog trunk route(TLU75)

[rokane]

Call originated from ISDN trunks route(PRI) cannot pass thru an analog trunk route. The call is disconnected outright when the route is seized.But if the terminating
party is local extension in MD it works alright. I already
checked the sig & other relevant parameters but I couldn't
make it works. Can anybody pls help me on this?


thanks.

The MD110 is running on BC10 software.

Have you check TCMAP?

Hello,
The traf is 00151515 for both trunk routes so I guest the TCMAP is not a problem.

You make an incoming selection from a PRI. This selection, pharaps manipulated by NUTRP, points to

1 - a DEST that engages the analog trunk
or
2 - a short number that contains the code of engagement of the analog trunk and a complete external number
or
3 - nothing of these

In case 1, how do you make the outgoing selection on analog trunk?

Another question: the BCAP of the analog route is correct for the kind of incoming ISDN call?

hello GioBs,

The MD setup is as follows;

route=60 , pri isdn trunk lines(incoming only)
route=75 , analog trunk lines with access "9" for outgoing
calls
extension number =6xxx

call scenario:

incoming caller from ISDN trunk lines dialed 9xxxxxxxx in which it should seized route 75 & should be connected to
pstn number xxxxxxx but it is not the case, the call is
dropped as soon as you seized the trunk line in route 75.

But if you dial 6555 the calls goes alright so my conclusion is that isdn originated calls cannot transit to
analog trunk route. But if callforward to external line extension 6555 to 9XXXXXXX & you call this number from
ISDN line it works.

You must set the dest 9 in this case (transit call)
not to seize ougoing line until whole number is received from ISDN .
Use NANLS and ADC=1... on the dest .
(Or create a dedicated dest for this usage)

Test the solution indicated from SYAR and give reply to us (I'm curious )

Hello everyone,

The isdn interface is now okay after I changed the Rodai
parameters with the BC12 example in the manual.

Original route data BC10;

ROU TYPE VARC VARI VARO
75 TL11 00000012 0000008A 000000D5
80 SL60 00008300 10080000 06400000

Route data copied from BC12 example;
80 SL60 00200010 45440000 06400000

I would like to thanks everyone for extending time
on this problem. Once again thank you all!
