CME and Avaya IP office PRI issues

[Jeff]

Hello, 

I am in need of a little help in my home telephony lab.  I recently added an Avaya IP Office 403 into the mix and I am connecting it to my 2851 via PRI.  I am not very familiar with the Avaya system, so my trouble shooting ability towards that is limited, but on the Cisco side I am receivng the following messages:

Global ISDN Switchtype = primary-ni
ISDN Serial0/1/0:23 interface
        dsl 1, interface ISDN Switchtype = primary-ni
    Layer 1 Status:
        ACTIVE
    Layer 2 Status:
        TEI = 0, Ces = 1, SAPI = 0, State = TEI_ASSIGNED
    Layer 3 Status:
        0 Active Layer 3 Call(s)
    Active dsl 1 CCBs = 0
    The Free Channel Mask:  0x807FFFFF
    Number of L2 Discards = 0, L2 Session ID = 83
    Total Allocated ISDN CCBs = 0

My router interface configs are as followes;

controller T1 0/1/0
 clock source internal
 cablelength short 133
 pri-group timeslots 1-24

interface Serial0/1/0:23
 no ip address
 encapsulation hdlc
 isdn switch-type primary-ni
 isdn incoming-voice voice
 no cdp enable

My router is providing the clock source.  I have attached a screen shot of the IP Office manager PRI config. 

Any help in getting these devices to communicate is greatly appreciated.

Thanks

If you want Cisco side to do clocking, you should also make it the ISDN Network side:

interface Serial0/1/0:23

 isdn protocol-emulate network

That should get the PRI up.

Brian, 
That did the trick.  Thanks for the info.
