Re: Utilising dialedDigits from LCF for routing

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

Hi Matthew,
 
For better troubleshooting, could you have 2 GnuGKs, where GnuGK1 will be receiving the call and sending it to the NonGnuGK and GnuGK2 will receive the call from the NonGnuGK, and see where to terminate?  Does this scenario work?
 
If no, then there is probably a problem with the termination plan?  Or, maybe the Non-GnuGK not handling the call as a potential setup and releasing the call?
 
If yes, then there could be a problem with GnuGK not handling the same call coming back again, as you described, in which case, can you have a completely clean GnuGK (no calls running), do exactly what you want, and have a level 5 debug output sent for better troubleshooting?  The previous debug output doesn't seem to be complete.
 
Regards
HASSAAN

Hi Hassaan,

 

Many thanks for your assistance ? I?ve tried both these options and I?m still having the same issue.

 

The problem I have seems to be two fold:

 

  1. Although the dialedDigits are being returned from the neighbor gatekeeper as 23415447818666888 the GNUGK seems to ignore this a revert back to the original number 447818666888.
  2. As the neighbor gatekeeper is only changing the dialedDigits and not adding any routing information (which is correct in this application) my GNUGK appears to be the end point (destination IP) and the originating client tries to set the call up directly to the GateKeeper ? which of course fails.

 

What I need to happen is the we send the dialled number to the neighbor GK to get the routing prefix added to the dialedDigits and then decide where to route from my GNUGK. I?ve obviously missed a setting somewhere but no matter what I try I can?t get it to behave. I have copied my Neighbor settings below for the gk adding the prefix.

 

[Neighbor::red.ben]

Host=195.195.195.195:1719

SendPrefixes=447

AcceptPrefixes=5

ForwardHopCount=6

NeighborTimeOut=5

AlwaysForwardLRQ=1

AcceptForwardedLRQ=1

IncludeDestinationInforInLCF=1

ForwardResponse=1

 

Any assistance anyone could give would be greatly appreciated.

 

Best Regards

 

Matt

You would need gateways registered to the gk with the appropriate prefix.  For this, you could have the gateways register themselves, or you could add permanent endpoints, and specify the prefixes in their config lines.  For example:

 

[RasSrv::PermanentEndpoints]

a.b.c.d=uk_mobile_d;23415

 

That line means that, a gw on a.b.c.d ip is registered as uk_mobil_d and is supposed to handle calls with prefix 23415.

Subject: Utilising dialedDigits from LCF for routing

 

Dear Sirs,

 

I have a scenario where I need to send a cell phone number to a neighbor gatekeeper (non-GNU) which identifies which network the phone belongs to. For example I send an LRQ for dialedDigits ?447818666888? to the remote system and it returns the network code as a prefix to this number, i.e. ?23415447818666888?.

 

The problem I have is then routing on the returned number ? I would like all the numbers prefixed 23415 to go to a certain gateway.

 

My Request and the Confirm:

locationRequest {

    requestSeqNum = 4

    destinationInfo = 1 entries {

      [0]=dialedDigits "447818666888"

      }

    }

    replyAddress = ipAddress {

      ip =  4 octets {

        c2 98 54 3c                                        ..T<

The problem I have is how do I route on the dialedDigits returned by the neighbour GK?

 

Many thanks for your assistance with this matter.
