Outbound SIP calling adding a "L"

I just setup an SBC 10.2 with SIP trunks to AT&T, IPO was already in place as version 11.1.

When making an outbound call, the sip header is adding a "L" in the "TO" field, for example To: <sip:15555551212L@10.21.1.10>
I cannot for the life of me figure out where this "L" is coming from, it is in the very first invite from IPO, so IPO is sending it. I tried multiple Sigma scripts on the SBC to try and remove it but no luck. Any suggetions?
 
Check with traceSBC who is sending this. Maybe a typo in your IPO config.
 
User Short Code, System Short Codes, ARS, SIP trunk call details configuration and… incoming call routes can be placed to search.
