2B channel transfer on a PRI with a MCIS 6.1 system

[hma3]

Okay, I have a MCIS 0x32 with a T-1 Card in PRI mode, and everything is installed and working just great. However I was asking our provider if we had the capability to transfer calls like we could with our old pots lines. After some waiting, they said that it would be possible to perform that action if our system could do a “2b channel transfer”.

Here is a description of the service, someone calls the office and we pick up the call. After discussing the issue, we determine that they need to be transferred to another service department outside our phone system. So we would call the external service center, introduce the initial caller to that center, and then remove ourselves from the call. Supposedly the system will then know that we are done with the call, and send a single to the phone company switch causing it to connect those two calls outside of our system, and freeing up our two channels.

I’ve asked my installer, and he believes this is just the conf/transfer feature, but I want to be sure we won’t be tying up channels doing this.
Thanks

I got a mixed feed back from that thread, Verizon says its possible if my equipment supports it. Now this is attached to a "Switch Type 5ESS", Would that indicate proper communication of the TBCT?

2b, or not 2b, that is the question. I saw the 2b stuff on another forum about 6 months ago, and I believe it is not supported, but please don't quote me on that. I personally have never dealt with it. Would like to know more about it though.

Conf/Transfer uses 2 channels and will tie them up through the length of the call. TBCT sends a signal back to the CO (on the same channel that the call came in on) to let the CO do the call transfer for you. That way it frees your lines up to receive other calls. The only system that I have heard the NORSTAR doing this with is a DMS 100. But if your carrier says that the 5e will do it then you should be able to test it. Just answer a call then use the link feature if you get dial tone back, call the other number let them answer then hang up. Then you can go under maintenace and look at your B Channels and see if they are not busy. Let us know

From a C.O. perspective, this is an option, your provider (Verizon) will need to make changes at their end to support this. At least with DMS's. I imagine the 5e is similar.

The company I used to work for sold this option as a 'product' and charged extra for it.

And like Hawks said, using conf/transfer will tie up the lines.

Yes, Verizon worked with us to test it when we cut over the PRI, however I don't believe our system responded correctly to verizon's switch. We have our CP100 doing a night call transfer to the company cell phone, but I can see on the smdr that the 2 channels are not released until someone hangs up.

Would it be a safe assumption that the norstar equipment will not work with Verizon's 5ESS? Or should I be trying a different function on our system to initiate this transfer?
