Yes, you can have two different numbers with TekTalk! You can even run them both through the same ATA!
This is an advanced feature which may require significant manual configuration of the device for the 2nd line. If your ATA was purchased from us, please contact us for assistance or click here if you have a Grandstream HT502. If your ATA was purchased from a third party, please contact their support line for information on how to set it up with multiple lines.
