CME - CallForward does not work when call is sent from IOS IVR

We have a problem where calls from our CME IOS IVR fail when they go to a DN which has CFB/CFNA set.

For example:

Caller dials the IOS IVR number 5257 (internally or from PSTN it makes no difference)

Selects option 1 from top menu and then option 1 again from the next menu

Call is transferred to DN7275

7275 is busy and has CFB set to forward to 7270 - at this point the call black holes

If 7275 weren't busy then the call can be answered normally

Also if you dial 7275 from directly and its busy CFB to 7270 works fine

The IVR script was configured using Stonevoice (not sure if that makes a difference) and we are using IOS 12.4(1a) SPServices.

Any advice/help on this issue would be appreciated.

TCL/IVR scripts need special support for transfers. If that is not coded properly, will fail. Ask Stonevoice if their script support transfers, or looking at it, I would be able to tell you if it does. Also, try transferring a call that you've received via script.

// IVR cannot transfer calls


The calls coming from the IVR can't be transferred to another ephone-dn.


That is a Cisco bug (ID - CSCse68221-), Cisco has communicated us the bug has been fixed in the

12.4(11)T1 release.
