Coverage
LiteNet has no local access numbers, no POP list and no roaming agreement. It has two ordinary US telephone numbers landing on two different modem pools, at two different speeds. If your telephone can dial the United States, you are covered.
Pennsylvania
Rate centre PHPHSBZN25, Pennsylvania — a Philadelphia-area rate centre in the 610 area code. This is the original dial-in number and the one with proven media: a real telephone call to it reached Asterisk, was answered, and produced 661 RTP packets for 660 frames with zero loss.
Carrier answering 16 lines at 2,400 bps In service since 1994
Boston
Rate centre HYDE PARK, Massachusetts. The seven digits spell 857-DIALUPS, which is the whole reason it exists: it says what the service is in a word an ordinary person decodes without being told.
V.32bis at 14,400 bps One line No PSTN call yet
This is the fast line. It answers one caller at a time with V.32bis capped at 14,400 bps and automode down to 1,200, so a slower modem still trains on it rather than failing. It has carried a synthetic call end to end through the dialplan at 14,400 — and it has never carried one from the public telephone network, which is why the sixteen-line Pennsylvania number is still the one to try first.
| Number | Rate centre | Area code in service | Spells | Proven |
|---|---|---|---|---|
| +1 610 922 1996 | PHPHSBZN25, Pennsylvania | January 1994 | — | Yes — clean audio on a live call |
| +1 857 342 5877 | Hyde Park, Massachusetts | May 2001 | 857-DIALUPS | Not yet — ordered, routed, in the dialplan |
Both numbers are assigned to the same carrier trunk group and both are matched by the same dialplan handler, so there is exactly one call path to reason about rather than two. Your account works on either.
Plainly: whatever your own telephone carrier charges for a call to a Pennsylvania or Massachusetts number. LiteNet charges nothing for the call, receives nothing from it, and has no way of seeing what you were billed.
Both are standard geographic US numbers. Neither is toll-free — calling them is not free to you. Neither is a premium-rate or shared-cost number — nobody is being billed extra and no revenue comes back to LiteNet. They are the same kind of number as a shop or a neighbour.
On most modern US plans a domestic call is included in the bundle and costs nothing extra. On a metered line, a legacy long-distance plan, a prepaid mobile or an international call, it costs whatever your provider's rate is. Check your own tariff before you leave a modem connected for three hours.
Anywhere that can dial a US number can reach LiteNet — dial +1 and the ten digits, with whatever international prefix your country uses. There is no geographic restriction, no allowlist and no registration of your calling number. A modem in Osaka gets the same carrier a modem in Reading does.
An ATA works, with a caveat that has nothing to do with LiteNet: modem tones survive uncompressed G.711 and are destroyed by the compressed codecs most VoIP providers prefer. If your adapter can be pinned to G.711 with echo cancellation and any “voice enhancement” turned off, a call will usually train. If it cannot, the modems will handshake and fail, repeatedly, and no amount of retrying will fix it.
The carrier trunk group is provisioned for sixteen simultaneous inbound calls and the answering pool runs sixteen lines, one thread each.

Sixteen is a hard ceiling in two independent places — the carrier will not deliver a seventeenth call, and the answering pool would reject one if it did. Both numbers draw from the same sixteen, so eleven people on the Boston number leaves five lines for Pennsylvania. There is no queue and no callback: a busy line is busy, and the honest answer is to try again in a few minutes.
