Huawei HG659 VOIP Probem (SIP)

I have bought Vodafone HG659 for another internet provider.

And I cannot use VOIP because the Vodafone HG659 reserved 5060 port for their VOIP.

To solve this problem, you need to upgrade HG659 firmware.

Here is the firmware.

Download it, and update it.

To connect an HG659 modem, you may need the admin account.

• Default username Admin
• Default password, either: @ and then the last eight digits of your modem's serial number. (E.g. @12345678)

Also, you need to uncheck the SIP ACL in the setting.  and delete all VOIP setting if VOIP is not working.
