The product sheet and another helpful forum post clearly states that the HWIC-1CE1T1-PRI does NOT support voice applications on the PRI, only data applications. However, running 15.2(1)T when we configure a PRI group, it seems to imply that it can support a voice application with a command option to the PRI-group.
dal-rtr02(config-controller)#pri-group timeslots 1-24
%PRI-group is created for data application only.
%For voice application, please remove this pri-group, then configure pri-group again with voice-dsp option.
What gives? I cannot find this command documented anywhere. What does the "voice-dsp" option for the "pri-group timeslots" do?
Should we assume this card can STILL not be used for SIP/TDM Voice gateway services?
Thanks for any tips/confirmation you can provide.
