> 2. If your network is partially TDM and partially VOIP, have you experienced any issues with either of them? What are your future concerns since STIR/SHAKEN does not work with TDM? 

We have a mix of TDM and SIP.  We are continuing to work towards an all 
SIP network.  However, our aging management is still stuck in the legacy 
mindset where TDM made us money (subsidies).  There are other reasons as 
well, such as simply a resistance to change, lack of knowing how 
something works can lead to a fear of it, etc.  I am hoping and praying 
that STIR/SHAKEN _NEVER_ works with TDM, so it forces our hand to an all 
SIP environment.

We have both SIP and TDM trunking with Inteliquent for toll sort of 
stuff.  All of our EAS trunks with neighboring telcos is still TDM only.

> 10. I tried to keep my list simple but I would love to hear your thoughts on anything I missed. 

For whatever reason, some telcos are simply marking everything as "A".
