[cisco-voip] PRI Issues

[Monica Hardy]

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?
