Hello, Everyone,

RE: Voice SIP Account Phone Number Not Accepting 2 Characters

My ISP TPG VoIP SIP account phone number is my TPG username rather than an actual normal telephone number.

When I enter my 2 characters TPG username 'xx' as my TPG VoIP SIP account phone number as the 'Phone Number' field in the 'Voice - SIP Account' modem router management page on the LAN IP 192.168.1.1, then I press the 'Save' button, I encounter the error message " The length of 'Phone Number' is out of range[3,32]."

I believe this error is due to my TPG SIP account Phone Number’ is not within the TD-VG3631 ‘Phone Number’ character length range from 3 to 32 inclusive.

My old modem can register to my TPG VoIP account successfully with my TPG username 'xx' as the VoIP SIP account phone number.

I have contacted my ISP TPG and tried to get an actual VoIP SIP phone number. However, TPG does not provide an actual VoIP SIP phone number to their customers. TPG states I should use my TPG username as my VoIP SIP account phone number. They ask me to contact TP-Link to resolve the aforementioned error.

Is there a way I can enter only 2 character TPG username as my VoIP SIP account phone number in the browser management page of the modem router? i.e. workaround, request TP-Link for a new firmware fix or else?

Any help will be greatly appreciated, thanks!
