I can't seem to find any information as far as whether the modular versions of the Cisco IAD like Cisco IAD2431-8FXS will allow you to terminate a SIP trunk and output a PRI.
I was trying to do this on a IAD 2435 but I have been unable to configure the T1 WAN port at all thus far:
LAB-IAD-2435#sh ver Cisco IOS Software, C2435 Software (C2435-ADVIPSERVICESK9-M), Version 15.1(4)M8, RELEASE SOFTWARE (fc2)

System image file is "flash:c2435-advipservicesk9-mz.151-4.M8.bin"

Thanks Chester! Your links point me in the right direction.
I must still be doing something wrong though, or doing unsupported function:
I have two 2435's connected with a T1 crossover cable. I never get successful ISDN negotiation with the PRI configuration. Details are below:

I had to add "clock source internal" on SIP-IN-PRI-OUT and "clock source line" on the PRI-DELIVERY-IAD but now the first still alternates between TEI_ASSIGNED & AWAITING_ESTABLISHMENT and the latter shows MULTIPLE_FRAME_ESTABLISHED. I am not sure this is normal behavior. I always thought if one side showed MULTIPLE_FRAME_ESTABLISHED the other would as well...

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
