Connect an Asterisk to PBX via E1 and tranfer calls Q.SIG?

Asterisk Asterisk Support
1

Hi guys,

here is the situation,

I need to connect a system to a Nortel Meridian 11 (and later on an Alcatel 4400) via an E1.

Ok all fine, the problem arises when I need to transfer a call from the E1 slot where I am handling it to an extension of the external PBX where the E1 comes from.

I know Q.Sig signaling allows this, but haven’t found a way to do this on Asterisk, Is it possible? Is there any other way?

thanks for any input.

PS
This is an extremelly useful feature since will allow to completely integrate an asterisk PBX with any other PBX which supports Q.SIG and act as only one PBX with a single set of extensions.

So if by any chance it is not done it is REALLY worthwhile doing it, and I volunteer to work on the project.

thanks

Manrique

I did something similar about 18 months ago, extension dialing between Cisco Call Managers and a Nortel Opt 81. Being in the US, I was using mutliple T1’s. I can’t imagine that the E1 signaling is that far removed, but anything’s possible.

Anyways, I tried qsig, and then ni2, before settling on dms-100 on the line protocol. QSIG and NI2 both “worked” to some extent, but dms-100 allowed for extension dialing from both sides without passing the full 10-digit caller id, as well as vmail functionality from the Cisco side to Meridian Mail. I never did get it to accept the # to skip entering the mailbox number from the Cisco phones though. That and the MWi. But other than that it works like a champ.

Let me know if you’re willing to try this and I’ll post or send you some sample configs for both systems. Not sure how dead set you are on using qsig.

cheers,
Will

Thanks a lot Will, I am in need to do this just don’t have Cisco, only Asterisk, do you think this could be done with it?

I’ll appreciate if you send me those config files to mfeoliyahoocom or post them here for others to help themselves too.

thank you very much

From my point of view this subject is of huge iportance for Asterisk’s future, given it will allow it to fully integrate to legacy PBX’s.

Has anyone else done it with Asterisk?

Is anyone willing to research along with me?

I can't seem to upload images, but I've got screenshots of these configs.  I'll email them to you.  If anyone else wants them can someone show me how to attach the images?

I’ll be trying my hand at integrating *, Nortel, and Cisco as soon as my request to use Asterisk has been approved by my legal group. I can’t imagine Cisco being any more difficult to configure than *. The config examples that I’ve seen for tying Cisco to * show similar configs (I mean the actual configs, not the interface for making those configs). I’m looking forward to trying it out.

cheers,
Will

Hi

I have similar problem. I need to transfer call using Q.SIG signalling and legacy Siemens PBX. I’m programmer and my knowledge about ISDN is very limited. For now I’m interesting is it possible at all? Please give me some advice.

Thanks in adivce.
