Landline in FTTH extension cable length

[Audioctor]

Thats a good option.. But will it work consistently with same settings? I have previously configured SIP with GS Wave app with another connection and it also had issues.

Anyone using it?

I have been using for almost 2 years now. I was facing similar inconsistency with my BSNL voice. So I configured it separately on an IPPBX. I have been happily using it ever since.
Infact, for this very reason, I would recommend BSNL FTTH to anyone who is serious about Landline. In my opinion such VoIP configuration is most straight forward in BSNL as compared to other operator's.

I have detailed this configuration in another thread on this forum.
