Hi Dipanjan,
Thanks a lot for your response.
your comments are really great help to me for further processing on this
issue.
However I was wondering if, is there any open-source alternative for this
solution??
Best Regards,
Aditya

Hi Aditya,
First thing, to connect an analog phone to any device that works in
digital domain, with signaling, you needs a POTS termination interface
(simply called line card). Easiest way is you can buy one simple ATA
(analog terminal adapter). E.g. Cisco ATA or D-Link SIP voice terminal
adapter.
Connect your phone to this adapter with normer phone cable (RJ-11) other
end, device to Asterisk server/PC would be an ethernet. the ATA shall take
care of understanding analog events coming from the phone and converting
them to standard SIP message and vice-cersa.
thanks,
Dipanjan

[SIPForum-discussion] Converting anolag to digital signaling
Hi,
I want to convert one existing landline(PSTN) phone to IP phone with
Asterisk .Already lab setup is done for IP phone.As, per my limited
knowledge MGCP/MEGACO can transalte PSTN signaling to IP N/W and also
there are some other hardwares which are converting ananlog phone to
digital IP phone.
Exactly I want the following call flow:-
Calling from one analog hardphone--convert signal(A/D)---->IP soft phone
------Asterisk------------->convert signal(D/A)------->analog hard phone
Can anybody please suggest me on how to resolve this issue.
Thanks in advance.
Adi
