HT813 SIP registration failed



  • Program – Bootloader – Core – Base –


The 813 will not register its account with the 6510. I am copying/pasting the password so I know it is being entered correctly. The log on the 6510 says nothing more than "SIP registration failed! The remote address is: IPV4/UDP/ but doesn’t give me any clue as to why it failed.


It would help to know what aspect of the HT, FXO or FXS and what ports are set in the HT.
