If you absolutely want to be sure, use 'pri intense debug span X' and watch for SETUP messages: < Protocol Discriminator: Q.931 (8) len=62 < Call Ref: len= 2 (reference 542/0x21E) (Originator) < Message type: SETUP (5) < [04 03 80 90 a2] < Bearer Capability (len= 5) [ Ext: 1 Q.931 Std: 0 Info transfer capability: Speech (0) < Ext: 1 Trans mode/rate: 64kbps, circuit-mode (16) < Ext: 1 User information layer 1: u-Law (34) < [18 03 a9 83 95] < Channel ID (len= 5) [ Ext: 1 IntID: Implicit PRI Spare: 0 Exclusive Dchan: 0 < ChanSel: Reserved < Ext: 1 Coding: 0 Number Specified Channel Type: 3 < Ext: 1 Channel: 21 ] You'll see the voice characteristics in the Bearer Capability details (I have NI-2, this might be different for NI-2 or other PRI variants). But as others have mentioned, generally T1 PRI = uLaw, E1 PRI = aLaw. -- j.
