Do US landline phones work in El Salvador?

Rip in Gle

A friend in El Salvador would like a phone with an answering machine and caller ID. Do phones purchased in the U.S. work in El Salvador? I did a little research and it appears they use the same caller ID standard, but I know, for example, that phones here meet FCC regulations, and I don't know if there are similar requirements in El Salvador, or different requirements that U.S. phones typically don't meet.
Just a quick note for other prospective answerers - yes, they have the same AC voltage, frequency, and plugs. I'm more concerned about switching and caller ID standards. Also, cordless phones transmit at frequencies assigned by the FCC and designed not to interfere with communications of other devices in the United States, but those bands aren't necessarily standard world-wide.

seriously? requirements for elsalvador that the US doesn't meet?

the US probably has some of the strictest standards for consumer products in just about every category that you can think of...

the think you should check to see if it is compatible would be the electrical power for the base of the answering machine/cordless phone... the phone should work fine down there.. i believe that they use the same outlets as us, but i would double check if i were you ...

EDIT-
" assigned by the FCC and designed not to interfere with communications of other devices" no, they just set aside a range of unlicensed frequencies for low power consumer electronics as far as telephones are concerned.. guess you have been lucky not to have much problem in the 2.4Ghz or 900 Mhz ranges, where there are way too many consumer electronic devices - wifi, cordless phones, baby monitors, wireless door bells, wireless video cameras, etc, etc, etc...

do not see the standard used in elsalvador, but would assume that they use bellcore FSK as the US does, so caller ID should be compatible.. http://en.wikipedia.org/wiki/Caller_ID

Is there a good landline phone, with LOUD volume & LOUD speakerphone, that works with Hearing Aids?

Dubber

I've heard there are telephones out there for the hearing impaired but what I am looking for is a land line telephone for my parents who wear hearing aids but refuse to wear them when using the phone. Both say they get ringing and feedback when using a cordless phone while wearing hearing aids, but when they remove them the volume of the phone isn't sufficient.

So...I am looking for a land line base phone, with speaker phone, and better than average volume and sound clarity. If possible, the phone system would come with one or more cordless phones, also with exceptional volume and sound clarity. Oh, I should also mention that they, and I, are very limited financially so can't spend a lot on this.

If a phone with these features doesn't exist, is there some sort of device that can be attached to the phone to increase volume and sound clarity?

Somewhat related, can anyone define a few things for me:

What is the difference between a 5.8 GHz, DEC 6.0, 9 GHz, and some other numbers and acronyms I can't recall atm.

Thank you for your help!

there are plenty of hearing aid compatible telephones http://www2.panasonic.com/webapp/wcs/stores/servlet/PNAEndecaSearchCmd?N=779832047&No=0&Nr=12001&Ns=&Ntk=MainSearch&URL=vShopSearch&cmTag=true&catalogId=13401&storeId=15001&Ntt=hearing+aid+compatible&cm_sp=SiteSearch-_-MainSearch-_-Consumer

DECT - Digital Enhanced Cordless Telecommunications these phones operate in the 1.9Ghz frequency range - an unlicensed spectrum that the FCC has set aside strictly for cordless telephones.. this is the latest and greatest in cordless phone technology...

5.8Ghz operates in this unlicensed spectrum, there are some other consumer wireless devices that operate in this spectrum, but it is one of the least crowded frequencies - however since it is the highest frequency cordless phone on the market, it also has the least range from handset to base (some 5.8 cordless phones also operate on the 2.4 Ghz spectrum)

2.4 Ghz operates on this unlicenced spectrum with many other consumer wireless devices such as WiFi routers, microwave ovens, wireless video cameras, etc...

900 Mhz phones operate on a crowded unlicensed frequency with many other consumer wireless devices, such as baby monitors, wireless speakers, garage door openers, car alarms, etc... also unless the phone has DSS then it is insecure and can be monitored by a radio scanner... (DECT, 2.4 and 5.8Ghz phones all have some form of DSS, or FHSS)

DSS - Digital Spread Spectrum - a form of encryption to prevent eavesdropping...

FHSS - Frequency Hopping Spread Spectrum - a form of encryption that also continuously searches for the best channel, and keeps changing to the best channel between the handset and base (normally these phones will not have a channel button, because the phone is constantly changing channels on its own)
