VOIP issues since being upgraded to new SH with R37
HI My Father uses a VOIP phone for calling relations in Australia and it has been working fine for years. Last week he was given a new modem (SH with R37) and since then the VOIP phone will not register with the VOIP provider. I have a SH with R36, so I took his phone home and connected it to my SH and it registered successfully, straight out of the bag so to speak. Took it back to his house, plugged it in, failed to register.
I am guessing that the SH R37 is somehow blocking the request to register, but have no idea what it could be. I have factory reset it and that made on difference, hoping somebody may be able to point me in the right direction on this one.
Thanks
SETCH
