Air route traffic control over San Antonio/Austin west to ELPaso

[VNR5338]

I'm new to the area and looking for the High, Ultra High air traffic frequencies for over San Antonio, Austin and westward to over El Paso TX. Thanks

Attached are my latest notes. There are some new ultra high sectors (FL360 and above), but I don't know the sector ID's (ZHU??), probably not using them now anyway with the reduced traffic.

Excellent. Much appreciated. Thank you AirScan.
