[cisco-voip] Dial Peers

Wed Aug 17 10:21:41 EDT 2011

Think I'm sorted for inbound and outbound dialing now.

No need for SPIDs

Just investigating codecs and Clocking now, as I'm running ISDN VTC over
the connection and its freezing even though the routers are back to back
at 100Meg full duplex.

If I am not mistaken dont you have to have SPID's defined under BRI ? I
have not played with BRI since CCNA days so I am rusty.

Ok.  I can see from debug isdn that number is "unallocated or
unassigned".  Where is dial-peer 1 pointing too?  Is that a CUCM?

I am trying to do the following

I think I have the dial peers correct but  a debug dial peers doesn't
show anything for an incoming call.
