I am a broadband cable provider and I have a lot of Arris TM4026 EMTA and would like to upgrade the firmware to SIP so that i can use them with my Asterisk server.

All my servers has public IP address that i could give you access to log in and perform this function.

Only people with knowledge should bid on this project as we have other sip based projects tha we would like to work with on an ongoing basis.
