[Asterisk-Users] Asterisk and SIP phones

You can turn on the md5 protection.

Sip.conf
[5551212]
....
auth=md5
md5secret=409ajlg0340j0h04jd0404jd0h04j (md5 Hash)

You have to put the passwords in the phones.

When a call is made to asterisk the PBX will send back and md5 hash that
the phone must answer correctly.

Also, pay for the static IP with the home office. Then put the static IP
in the sip.conf file.

Sip.conf
[5551212]
....
host=192.168.1.1
...
auth=md5
md5secret=409ajlg0340j0h04jd0404jd0h04j (md5 Hash)

PS. I am currently building a RADIUS based md5 registration, incoming
and outgoing call SIP channel for asterisk. This channel requires every
registration and call to verify with RADIUS first.

Subject: [Asterisk-Users] Asterisk and SIP phones

I have Asterisk server providing phone service for my company.
The server is behind a PIX-515 FW and is assigned a private address
192.168.11.X/24.

With that said what is best to provide remote SIP phones (home offices)
securely.

If the solution is to put up another Asterisk server with a public IP
address I am opposed to that.
I am looking for the a secure reliable solution to set up remote SIP
phones.

Thanks in Advance.
