RE: [Sip-implementors] SIP phone to PBX connection

[Fred Sullivan]

Brian - thanks ! this is exactly what I was hoping I could use. Im sure this kind of a device (which hopefully is lowcost) will surely help any migrator/tester for SIP to make it a little more realistic to convince cynical organizations to plan a stepped migration.

To help myself in understanding exactly this device you suggest, it will:

1) Allow me to make SIP calls as usual

2) Use  the same SIP phone to make calls to other phones in the PBX ? ( I am doubtful about this one - since I assume that will need a SIP gateway - and then I guess the vendor must support SIP in his device - if this is true, I dont how how many commercial solns exists today which cost less than multi-thousands :-) )

 

Finally, one of the PBX systems here is a Nortel Meridian. Could you suggest whether this is supported and where I need to look ?

[Again, to re-iterate, my intention right now is to use one SIP phone (cisco, pingtel or any other) to talk to other PBX phones (simple call will do) besides talking to other SIP phones. I dont care about SIP-PBX world feature interop as of now/

Actually, you can buy a gateway that has digital PBX ports on one side,

and a SIP UA through an ethernet connector on the other side.

 

The hitch is that the box only works with a limited set of PBX types.

 

You can also get a board that provides emulation for the PBX phones

that will plug into a PC.  It has multiple ports per board.  You then

have to interface this to a SIP UA, which is not very complex for

basic call, but can be quite complex if you want to emulate all the

features the phone can do.  The advantage of the box is that it

does this (although it's a new box, so the feature set is not

complete yet).

Subject: [Sip-implementors] SIP phone to PBX connection

Hi, my organization uses a digital PBX. I recently bought some SIP phones and I want to convince my team to use these phones instead of the current phones.

However, to do this, I must be able to allow the SIP phone uses to dial other people in the organization thru the PBX. Now, I doubt I can work with the MIS folks here.

So, my question is this:

Is it possible for me to buy and cheap hardware that I can connect to my PC which can directly provide a connection to my digital PBX port ? If so, then I can run a SIP server on my PC that can then forward non SIP calls to this line and it can use the PBX to make these calls.

 

Thanks

Mark
