Asterisk and one rj11

I’m trying to setup something at work for testing purposes. I want to have asterisk use the company’s phone lines on outbound calls and inbound calls going to a hardphone.

On my desk, I have one cat5 cable, one digital phone and one Rj-11. I know there is a PBX somewhere, but it doesn’t work with IP phones (IT guy told me). I don’t think the rj-11 is connected directly to the phone company. I have to dial 9 before a number

It was setup half a decade ago and the IT guy is for all intent and purposes not there to help me (makes more money in the sales department).

It was suggested to me to use a obi110.Will this work in this case?

(sorry if its a noob question, I have no idea how older PBXes work)

Why don’t you ask to the IT guy the name and model of the Analog PBX of your company, that could help to figure the Topology of your company’s telephone system. And based on that Topology we could provide you a solutions based on Asterisk.

This is not a support forum, even though it receives a lot of off topic postings.

Especially given your lack of telephony knowledge, is something than really needs to be done by the IT people, or not at all.

On the information provided, it is not certain that your phone is a simple analogue phone; it may be a custom digital phone for the PABX.

Running VoIP over a corporate network and achieving reasonable quality normally requires reconfiguration of the internal routers.

If it is an analogue phone, typical office analogue phones are the same as touch-tone PSTN phones, except that, in the UK, at least, they will normally use earth recall rather than timed break/flash recall.
Typical PABXes do not provide answer or disconnect supervision on extensions, so it may not be possible to wait for answer on outgoing calls, and it may be necessary to clear all calls from the local end.

The obi110 is something for “putting you in control of your communications life”, and not being able to read through marketese I can’t tell for certain whether the way it achieves that is useful, even if you have simple analogue extension. My guess, though, is that it is an ATA, which does the opposite of what you want to to (i.e. allow an analogue phone to be used on a SIP telephone network).
