Hi -
Here is the link to micro trace files - http://www.cisco.com/en/US/customer/products/sw/voicesw/ps2237/prod_troubleshooting_guide_chapter09186a0080449d74.html#wp1129423
Specifically - MiuIntegration
Integrations with circuit-switched phone systems; call information in integrations with circuit-switched phone systems; turning message waiting indicators (MWIs) on and off in integrations with circuit-switched phone systems. I also found this in the 4.2 troubleshooting addendum, "PIMG Units Produce Unexpected Results
When Cisco Unity is integrated via PIMG units to a circuit-switched phone system, and the PIMG units are not producing calls or call information as Cisco Unity requires, perform the applicable diagnostic tasks for the PIMG units that the manufacturer suggests. Detailed instructions are in the "Diagnostics" chapter of the Intel Netstructure PBX-IP Media Gateway User's Guide, which is available at the Intel website." We will be moving in this direction - Avaya G3R and PIMG. I would be interested in any issues you've had and how you dealt with them (including this one). You may e-mail me at kavang@saccounty.net. I would much appreciate your insight and experience! P.S. Just found the Intel guide I think Cisco was referring to - http://resource.intel.com/telecom/support/pimg/manuals/c73213-001.pdf
Sincerely,
Ginger
