Analog Trunk - Limitations? 1

[OldSchool70]

Have a customer that wants a new IP Office but only wants to use analog trunks. What are the limitations of using only analog trunks as it pertains to the IP Office features and functionality?

You can't use twinning. You can't control your outbound callerID. You can only have 2 external participants on a conference. IP phones tend to have quality issues with analog trunks (especially VOIP converted to analog trunks). Im guessing they want analog lines to use line appearances which should be avoided in Standard Mode (and Basic mode should be avoided all together).

I am sure there are more.

The truth is just an excuse for lack of imagination.

No DDi's, limited capacity and a short life expectancy as most providers are ceasing or planing to cease support for analog lines.
there is n place for analog lines in the modern world.
Seriously do your self & your customer a huge favour & make them drag their operating processes into the 19th century

(I am pretty certain you already know this & just wanted extra information to help with the process of educating the end user)


Do things on the cheap & it will cost you dear

No warning if out of service.

What's the alternative?

So, you can use a twinning button to enable/disable, utilizing an analog trunk. BUT, it will treat teh call like it was forwarded. So no twinning features like, pulling the call back, original calling party CID, etc...you get none of the twinning features...

Get a SIP trunk, and just use that for the outbound twinned call...

Moving to SIP trunks was the best move I ever made!

Thank you for all your responses. Very helpful!

Depending on where you are, there's a high chance your analog connection will be provided by a SIP gateway device converting SIP to analog.

Stuck in a never ending cycle of file copying.

Like sizbut said it is a very high chance that it will come in as SIP and then be converted to analog. This means you are literally paying extra for lesser functionality. The only advantage (I can think of that is) to having analog is when there is a power failure and with SIP converted to analog you would lose that advantage because if you lose power your SIP gateway is down. Just go with SIP trunks if at all possible.

The truth is just an excuse for lack of imagination.

Depending on your location, we have been very happy with NexVortex. White Label is also pretty solid for SIP Trunking.

Both were pretty easy to configure on an ASBCE.
