Looking for a replacement for the Telstra T-Voice 503 DECT phone?

TSH-C-QSGI took a gamble on the Telstra Smart Handset Cordless Handset (TSH-C) and it worked.


The charging base is not compatible with the T-Voice 503.

Other things to know

Only compatible with these Telstra modems:

  • Telstra Gateway 5358
  • Smart Modem Gen 1
  • Smart Modem Gen 2
