Issue with call to voice mail from PSTN

Hi, 

Have a weird issue.  Details below:

When you call in to the VM from the PSTN the call immediately fails but if you
ring from on net VM is fine.  I have done numerous debugs and the only thing i
can find is the debug on the telephony leg between the AXE and Cisco Voice
Gateway.  Debug below:

Dec 30 09:33:35: ISDN Se0:15 Q931: RX <- SETUP pd = 8  callref = 0x001E
        Bearer Capability i = 0x9090A3
                Standard = CCITT
                Transfer Capability = 3.1kHz Audio
                Transfer Mode = Circuit
                Transfer Rate = 64 kbit/s
        Channel ID i = 0xA18381
                Preferred, Channel 1
        Progress Ind i = 0x8A81 - Call not end-to-end ISDN, may have in-band
info 
        Calling Party Number i = 0x2183, '8005284280'
                Plan:ISDN, Type:National
        Called Party Number i = 0x81, '80234333'
                Plan:ISDN, Type:Unknown
Dec 30 09:33:35: ISDN Se0:15 Q931: TX -> SETUP_ACK pd = 8  callref = 0x801E
        Channel ID i = 0xA98381
                Exclusive, Channel 1
Dec 30 09:33:36: ISDN Se0:15 Q931: TX -> CALL_PROC pd = 8  callref = 0x801E
Dec 30 09:33:36: ISDN Se0:15 Q931: TX -> FACILITY pd = 8  callref = 0x801E
        Facility i =
0x9FAA068001008201008B0100A1150202084E020114300C0A01010A0102800437303030
        - Unknown Service Discriminator
Dec 30 09:33:36: ISDN Se0:15 Q931: TX -> ALERTING pd = 8  callref = 0x801E
Dec 30 09:33:36: ISDN Se0:15 Q931: RX <- STATUS pd = 8  callref = 0x001E
        Cause i = 0x829F - Normal, unspecified
        Call State i = 0x09
Dec 30 09:33:36: ISDN Se0:15 Q931: TX -> RELEASE pd = 8  callref = 0x801E
        Cause i = 0x80E5 - Message not compatible with call state
Dec 30 09:33:36: ISDN Se0:15 Q931: RX <- RELEASE_COMP pd = 8  callref = 0x001E


Topology is:

Mitel (pots) Cisco Rtr (voip) Cisco RTR (POTS) AXE.

I found this on the Cisco Website:

The remote equipment receives an invalid message with no standard cause.

This cause indicates that the equipment receives a message that is not
permissible in the call state according to the procedures. This cause can also
indicate that the equipment receives a STATUS message to indicate an
incompatible call state.

The issue occurs due to a D-channel error. If the error recurs, report the error
to your ISDN service provider.




Anyone ever come across this?

All i can think is to upgrade the IOS.

Cheers

Kev

Re: Issue with call to voice mail from PSTN

I fixed this by removing the IE from the h32 using voice signal none.

Turned out the Voice PSTN Gateway had issues with it.

Cheers
