call forwarding from a mobile phone to a cisco ios gateway does not work

We have a german "anlagenanschluss" connected with 4 isdn voice bri channels to a cisco 3640 router. If a call to a mobile phone is forwarded to the router the call is disconnected.

deb isdn q931 and isdn error show the following output:

Apr 15 11:21:07.292: ISDN BR1/0 Q931: RX <- SETUP pd = 8 callref = 0x35

Sending Complete

Bearer Capability i = 0x8090A3

Apr 15 11:21:11.424: ISDN BR1/0 Q931: TX -> RELEASE_COMP pd = 8 callref = 0xB5

Cause i = 0x80D1 - Invalid call reference value

the bearer cap is the same as with a simple incoming call (which works fine).

config of the isdn interface:

interface BRI1/1

no ip address

no logging event link-status

isdn switch-type basic-net3

isdn overlap-receiving T302 2000

isdn incoming-voice voice

isdn static-tei 0

maybe anyone has an idea about problem

thanks in advance

Re: call forwarding from a mobile phone to a cisco ios gateway d

Hi,

we had to use this command in all of our installation

isdn sending-complete

to solve forwarding problems.

Maybe this will help.

You are not alone.

Same with a 3725. We get the same Output.

TAC said resolved with 12.2.15T2 but its all the same.

Did you find a Solution for your 3640, as TAC says it only applies to the 3700 Routers.

You are definitely not alone.

We had the exactly same issue with the MRP200/300 on the ICS-7750.

The IOS gateway had problems as soon as it saw ISDN facilities.

We opened a TAC case and the output was a IOS that worked!

We are still waiting for the bug fix in the proper IOS releases - for the MRP we now have a "hand-knitted" software ...

The bug ID was CSCdz46826 , the case was closed last december.

Cheers,

Martin

Re: call forwarding from a mobile phone to a cisco ios gateway d

That´s good to know,

today I tried also 12.2(15)T2 and the problem stays the same.

Hopefully it will be resolved in the next upcoming release because we don´t have many choices regarding the IOS must be a high 12.2 release...

Maybe if anyone of you knows anything new about this issue please post it, I will do the same.

Thanks

Re: call forwarding from a mobile phone to a cisco ios gateway d

Hi Guys,

yesterday I tried the very new 12.3.1 release on the voice router and wonder how, the bug is fixed the call forwarding works.

I also tried it with 12.2.16 it also has worked but the calling number was not shown correctly. This also works with 12.3.1.
