3

Very rarely in lab conditions

Symptom: Voice Browser prints log errors for

 

 

with high transfer rate, ISN can

"Invalid sequence number" during transfer.

 

 

drop call

When these occur it happens almost always

 

 

 

at the time of call disconnect, so there is no

 

 

 

effect to the caller (since they are already

 

 

 

gone). However, very rarely this error may

 

 

 

occur while the call is active. In such cases,

 

 

 

the caller will be abnormally disconnected.

 

 

 

Conditions: This very rarely occurs, and seems

 

 

 

to be only under lab conditions when a transfer

 

 

 

load through the Voice Browser is excessively

 

 

 

high.

 

 

 

Workaround: None

Timed out from Voice browser

In very rare circumstances, there is an

 

 

error shouldn’t happen

unexplained error in the Application Server log

 

 

 

files. The log reports that the Application

 

 

 

Server "Timed out waiting for Call Result from

 

 

 

Voice Browser". This error shouldn't happen.

 

 

 

There aren't any workarounds for this problem.

ISN is not supported with NIC

The ISN does not respond to an ICM release if

 

 

in VRU Type 7 call flow

it is busy with another script node. When the

 

 

 

ISN is acting as a Type 7 Network VRU and

 

 

 

the call needs to be taken away from the VRU

 

 

 

to be connected to an agent, it should release

 

 

 

the call for a transfer but does not, which

 

 

 

means the call cannot be transferred. When

 

 

 

the ISN is acting as the switch (routing client)

 

 

 

in a VRU Type 7 call flow, the ISN does not

 

 

 

respond to the ICM release, but sees the VRU

 

 

 

leg hang up. If the caller does not hang up

 

 

 

within 2 seconds (ISN Release 2.0), the ISN

 

 

 

will hang up. It should be noted that in the

 

 

 

presence of ICM defect CSCma18392 (release

 

 

 

4.6.2), the ICM does not send a release

 

 

 

message to the IVR leg of the call when using

 

 

 

a VRU Type 7 call flow. As a result, in the

 

 

 

presence of both of these problems, the

 

 

 

behavior is the same as described above even

 

 

 

when the ISN is not busy with another script

 

 

 

node. Additionally if the VRU leg does not

 

 

 

release the call, the ISN acting as the switch

 

 

 

will restart the call if configured to do so and

 

 

 

the caller has not yet hung up.
