[cisco-voip] PRI Issues

On outbound calls, do you have the setting to send the Redirecting Number checked? If so, that sounds like what is going on. For outbound, there's likely no reason to have that enabled.

 

Thanks,

Hello everyone,

I am hoping someone could shed some light.

 

I have 2 PRI's on one MGCP GW and 2 more on another MCCP GW.  I have set them up identical.

 

All 4 PRI's are part of the same RG.

 

We have a toll free number from a provider that forwards to a number in our DID range.  After the call comes in it is then forwarded to an international number.

 

888 Incoming number à forwarded to extension in our DID rangeà this extension is CF to a international number

 

 On one of the gateways if I set the 'Calling Party Selection ' to 'Last Redirect Number(external) the call goes through.  If I leave it set on 'Originate' the call fails and this is what I see in the debug:

 

Aug  3 16:40:39.553: ISDN Se0/0/1:23 Q931: TX -> CONNECT_ACK pd = 8  callref = 0x000E

Aug  3 16:40:56.937: ISDN Se0/0/0:23 Q931: TX -> SETUP pd = 8  callref = 0x0010 

        Bearer Capability i = 0x8090A2 

                Standard = CCITT 

                Transfer Capability = Speech  

                Transfer Mode = Circuit 

                Transfer Rate = 64 kbit/s 

        Channel ID i = 0xA98396 

                Exclusive, Channel 22 

        Calling Party Number i = 0x2183, '91650743XXXX' 

                Plan:ISDN, Type:National 

        Called Party Number i = 0x80, '01144208814XXXX' 

                Plan:Unknown, Type:Unknown

Aug  3 16:40:57.057: ISDN Se0/0/0:23 Q931: RX <- CALL_PROC pd = 8  callref = 0x8010 

        Channel ID i = 0xA98396 

                Exclusive, Channel 22

a 91 is added to the Calling Party Number, so the call fails.  It only does this on one of the Gateways.  On the other the 'Originator' setting works fine.

 

I can't figure out where this 91 is coming from and why it would only come on one gateway and not the other.

 

Any ideas?
