Dear All,

 

Call from PSTN Phone to Head Office Router is successful but when I am dialing from Head Office to PSTN phone it's showing unallocated /unassigned number error.

 

*Apr  7 19:28:36.494: ISDN Se1/0:23 Q931: Applying typeplan for sw-type 0xD is 0x2 0x1, Calling num 6178631002
*Apr  7 19:28:36.502: ISDN Se1/0:23 Q931: Applying typeplan for sw-type 0xD is 0x2 0x1, Called num 2123942123
*Apr  7 19:28:36.506: ISDN Se1/0:23 Q931: TX -> SETUP pd = 8  callref = 0x0095
        Bearer Capability i = 0x8090A2
                Standard = CCITT
                Transfer Capability = Speech 
                Transfer Mode = Circuit
                Transfer Rate = 64 kbit/s
        Channel ID i = 0xA98383
                Exclusive, Channel 3
        Calling Party Number i = 0x2181, '6178631002'
                Plan:ISDN, Type:National
        Called Party Number i = 0xA1, '2123942123'
                Plan:ISDN, Type:National
*Apr  7 19:28:36.542: ISDN Se1/0:23 Q931: RX <- CALL_PROC pd = 8  callref = 0x8095
        Channel ID i = 0xA98383
                Exclusive, Channel 3
*Apr  7 19:28:36.550: ISDN Se1/0:23 Q931: RX <- DISCONNECT pd = 8  callref = 0x8095
        Cause i = 0x8281 - Unallocated/unassigned number
*Apr  7 19:28:36.570: ISDN Se1/0:23 Q931: TX -> RELEASE pd = 8  callref = 0x0095
*Apr  7 19:28:36.586: ISDN Se1/0:23 Q931: RX <- RELEASE_COMP pd = 8  callref = 0x8095

    Hi Cisco

     

    Run a isdn q931 on HQ and see what number is really coming it. If telco saying it is unassigned it is unassigned.

     

    I assume you can make national calls etc. Also check telco does not require SPID etc

    Hi,

     

    I guess you are missing digits.

    That is most probably what is causing you unallocated/unassigned number error.

    What does the phone do? What do you ear?

     

    Are you sure you are sending the necessary digits, so you provider can route the call ?

     

    Thanks,

    Ruly

    Re: QUESTION:Unallocated/unassigned number error

    I agree about running the debug on the other side.  If your topology has a switch in the middle (like an Adtran Atlas 800, or something like that) it may be a lack of mapping on that ISDN switch giving that code.

     

    Or, as noted, it could be on the other side.

     

    But someplace, somebody isn't getting what they are expecting!

         The first thing I would look at is to verify with your carrier that your ISDN circuit is actually designated for National service and that your PRI switch type is correct. Thats usualy whats wrong when I see this error. To quickly test the plan type you can switch the gateway to unknown in CallManager and then try sending the number both with and without a 1 to see if it connects. If not then verify the switch type with your carrier.

     

    Let us know how it turns out and good luck,

    Re: QUESTION:Unallocated/unassigned number error

    So it's like routing...

     

    Each step along the way needs to know where to do and what to do with it.

     

    Coming IN, your route is to the destination phone number (DN) which exists on the local device/network.

     

    Going OUT, your route is a handoff to the PSTN (presumably) based on digit matching.  If YOU have matched a pattern and hand it off to the other side, then THEY need to have a pattern match for it as well.  Eventually it gets someplace that doesn't for that specific number.  And therefore it can't go anywhere.  Kinda like getting an "icmp unreachable" in the IP packet world!

     

    HTH,

    Hi Abdullah

     

    Can we see the ISDN Q931 debug. Edit the text to change the last six digits to 123456 for security.

    Re: QUESTION:Unallocated/unassigned number error

    Hi Scott

     

    I understand what you saying and it makes, I do have matching going out from my MGCP gateway, but when it get to the other side which is my PSTN (CME) it doesn't find any matching even though I have 911 in place as dial-peer. If I take of direct-inward-dial  from the incoming dial peer the call reaches to the CME PSTN and givee me another dial tone which then I need to re-type 911 from my HQ phone and the PSTN phone rings. So there for I think there is something wrong with my dial peer end in the PSTN router. PSTN router have  VWIC-E1-MFT-G703 2 port using xover cable between HQ and PSTN router.

     

    I really appreciate your respond

     

    Thanks

    Re: QUESTION:Unallocated/unassigned number error

    Hi Abdullah

     

    +17752011001  are you present DID eg 1001 to the other end and does 1001 exist?

    I am guessing it is four digits.

    Thanks Conwyn for your respond

     

    let me tell you how my line is configured I am using 7975 phone to make my phone call CUCM Devices phone select the phone from CUCM

    Line 1 has got 1001

    External phone number Mask +1775201XXXX

    under the service parameter I have changed stop Routing on unallocated number flag to (false).

    on the MGCP CUCM inbound calls significant digits 4

     

    Yes the line has got 4 digits. on the MGW router I only have mgcp configured no dial-peer exist in the HQ everything is controlled by CUCM and I am using ISDN net5
