Cisco3640 with signaling R2

We are connecting a PBX Harris to a Cisco 3640 with I module Nm-hdv-1e1-30e, using signalling R2 for Mexico; connected with voip to a 1750 using E&M. Las sessiones of Voip they stay, but I do not obtain tone to mark digits in both PBX, and nothinh is listened. A question is under this configuration when from the PBX I take hold a voice channel in the Cisco this to router must provied a tone to mark to me?.

They have some ideas o recomendation about this.
