How to configure Bsnl ftth Voip on softphone? Unable to ping SIP in cmd.

[AM9656]

'REGISTER sip:$domain SIP/2.0\r\n'
'Via: SIP/2.0/UDP $clientIP:$port;branch=z9hG4bK${uuid.v4()}\r\n'
'Max-Forwards: 70\r\n'
'To: <sip:$username@$domain>\r\n'
'From: <sip:$username@$domain>;tag=${uuid.v4()}\r\n'
'Call-ID: $callID\r\n'
'CSeq: $cseq REGISTER\r\n'
'Contact: <sip:$username@$clientIP:$port>\r\n'
'Expires: 3600\r\n'
'Content-Length: 0\r\n\r\n';


I am not getting any response from the server when I send this message. Port I'm using is 5060, Domain and username provided by BSNL and getting my localIP for clientIP

is proxy necessary for BSNL?

So I tried this in 2025 I made static routes and everything but I could only ping the sip domain thru VoIP wan in router network diagnostics when I tried the same via internet wan it fails what do I do or is it only accessible in VoIP wan ?

SIP domain, SIP server will be available via Voip WAN only.
That's the reason you add a static route to use Voip WAN for these.
