Why converting an Age Old Normal Telephone to an IP Phone is not all feasible?

[prabha_friend]

What's the design and production cost if at all one wanna design and manufacture his own IP phone or want to convert an old phone to an IP phone.

 

[prabha_friend]

I think the entire problem would be solved if we find a cheaper way to provide an ip address to an analog phone…

 

[prabha_friend]

Is assigning ip address that much hard? We just need an unique MAC for each of the phones in line...

Analog phones could be connected to PCs back in the days when MS-DOS was involved, but somewhere along the evolution of PCs, they converted to using physically different connectors that no longer use the same type of circuitry. The problem wouldn't necessarily be getting an IP address if you could make the connection, it would be getting the old phone to respond to digital signals in the first place. For that you need intelligent modems. Assigning an address MIGHT be as simple as using DCHP behind a multi-line modem. Digital Equipment Corporation (now defunct) used to make 8-channel or 16-channel multiplex modems. The U.S. Navy had tons of them in the early 1990s but as networking moved more towards Ethernet, the multiplexers started to be retired. The other trick, though, was to have a working voice over IP style of phone, you would ALSO need a voder/vocoder combo, and that ALSO has gone the way of history.

You might be able to find what you want in shops that carry old parts, but I'm going to bet against it being THAT easy to find. By they time you bought what you needed for the old phones and paid someone to string them together, it would be cheaper to get modern phones that have all that stuff built-in.

I cannot do that. It isn't my area of expertise. Perhaps someone else would be able to suggest something for you. But a web search should be enough for what you wanted.

I'm not as polite as The_Doc_Man, perhaps, but I'm wondering why you are here at an Access centric forum, asking people to search the internet on your behalf for equipment that is, at best, outdated?

I am trying to open some new windows Here... As all my posts are interrelated. There's a link between access database to asterisk and Asterisk to my current project of making my own SIP communication device.

 

[prabha_friend]

Kindly like this reply if you don't want me to post anything other than ms access here...

 

[GPGeorge]

Perhaps I was not clear.

The problem is asking others to search for links on your behalf, e.g. find you information about microphones and speakers.

" Please suggest me an affordable microphone and Speaker for my project. "

Assumptions! I am trying my luck to find a person who has already done it. Most of the times my luck works! Rarely assumed upon. I am not that lazy enough to not make Google atleast in the first hand. In your view everyone here know only ms access. In my view, I just ask the questions the right one will answer others will ignore. Answers are precious!

Assumptions? have not suggested that anyone here or anywhere else "knows only MS Access". That's how you choose to frame it and that reflects your opinion.

How about this, then. Apparently, you've already Googled for equipment.

You claimed, "I am not that lazy enough to not make Google at least in the first hand."

Am I right in assuming that means you have already conducted that search and found links to potential microphones and speakers? If so, maybe you can post YOUR findings and ask for people's opinions, pro or con, about each one.

Hi George. Kindly excuse my tone in my previous post. I didn't mean the same. See i usually post all my questions across 3 forums. Here, allaboutcircuits.com and community.asterisk.org. You won't believe a fact. All the members in all the 3 sites are equally interested in answering a new question. Whether it's related or not.

 

[prabha_friend]

Some questions can't be answered properly by Google itself

I absolutely agree that Google is a miasma of irrelevance.

But does this mean that you have searched for relevant equipment and found nothing?

Be aware that you have just admitted to previously unannounced cross-posting, which is considered impolite. When you post the same question on multiple different forums, you potentially dilute/diminish the value of any help we can give here.

FWIW I think it makes the forum pleasantly surprising when people post odd ball out postings, b/c you never know - I recently posted something about powershell but I did it in the 'windows' forum (or something like that), and although I expected zero answers I wouldn't have expected a spanking.

@GPGeorge I liked your post because you taught me a new word! Thanks

In general you can post anything you like on this forum, subject to the forum rules, which I think you will find are very relaxed....

I understand that some people are irritated by certain types of post which they don't believe should be on an MS Access forum.

For these people there is a simple solution, they can block a particular individual so that they do not see that person's posts anymore. They can block complete forum sections so they do not receive any information from those.. I'm not 100% sure how forum section blocking works because I've never used it.

I'm often taken aback by my inability to express things clearly.

The reason I questioned the original request for assistance in finding specific telephony equipment was that it seemed to be a request for assistance doing something the OP could just as easily search for himself.

It had nothing to do with the request being non-Access specific. I was surprised that this request was made here because some very high percentage of the participants are here because of their interest in Access and Access related subjects. I doubt more than a handful are here for the telephony posts.

I thought it was odd that this would be the venue chosen for a question about telephony equipment given the slight nexus between Access and telephone switchboards. I would have thought that would be more likely to get a useful response in a forum devoted to, oh, say, old fashioned telephone switchboards. Somehow that got twisted into objecting to non-Access questions. My bad. I did not spell that out carefully, merely noting that this is an Access-centric forum.

I apologize for sparking a row.

On the other hand, apparently an appropriate internet search has now been conducted, and post #17 has links to the equipment in question!
