A small detour worth taking
Pick up the phone, choose a Hall & Oates song, and enjoy the telephone jukebox. The song choices belong to the music menu—you select them after the call connects.
Call 646-827-6222 ↗From ChazTel or PhreakNet, dial 266-9999.
03 / Get connected
A SIP phone, a softphone, or an ATA with an analogue telephone can bring you onto ChazTel.
Use a SIP desk phone, an Android softphone such as Sipnetic, or MicroSIP on Windows. An analogue telephone adapter lets you connect a traditional phone.
Email your name, a PSTN callback number, and the equipment you want to use. Mention voicemail, multiple phones, or an existing number you want to bring along.
Chaz will arrange an extension and provide your connection details. Configure your device, check that it registers, and test an internal call and an outside call.
For ChazTel compatibility, enable G.722, G.711 A-law, and G.711 μ-law, in that preference order. In Sipnetic, find these under Settings → Audio and video codecs. Keep the exact choices consistent with the settings Chaz gives you.
Chaz can help arrange incoming DID routing. Bringing a PSTN number requires your own Telnyx account and responsibility for your number and call charges. Discuss the port before making changes. Provide only the SIP connection credentials needed for the setup, through an agreed private channel—never your Telnyx account password.
Voicemail is available on request. Dial 69100, enter your four-digit mailbox number, and then your voicemail PIN. A compatible phone or ATA can display a message-waiting indicator. The existing setup uses a temporary greeting: choose 0 for mailbox options, then 4 to record it. You can also change your voicemail PIN in mailbox options.
The device’s dialing rules need to allow full numbers, including 011 international calls and area codes beginning with 4 or 6. Ask Chaz to review the digit map rather than trying to solve it with extra prefixes.
Protection depends on your device, connection, and the networks involved. Ask Chaz about encryption for your setup. A call that enters the public telephone network does not become end-to-end encrypted simply because it started on ChazTel.
