Thank you, Jason Miller -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of James Taylor Sent: Monday, April 04, 2005 11:43 AM To: [email protected] Subject: [Asterisk-Users] FGD Support For those of you who want to look like a "real" phone company, and plan on connecting to the LEC so that you look like a long distance carrier instead of a customer, there are some mods to the ZAP channel which must be made. When you order Feature Group D as a "customer" Asterisk works fine right now. If you order Feature Group D and want to provide service as a IC or IXC (long distance carrier) and provide Equal Access, you must "look" like an Equal Access End Office (EAEO). To do this, there is an additional packet that must be exchanged and acknowledged in the dialing sequence. I have submitted a request to Digium for a quote on this modification. Jason Miller at interlinc.net has added his spport to this project, because he needs it working yesterday. If you have an interest and would like to assist in getting this modification off the ground and completed quickly, then you might want to contribute financially. If you have an interest and can't contribute, we'd still like to hear from you and know that this feature might help you. Contact me off list if you can help.

Please let me know what the charges will be, so we can get approval and get started. As more and more Asterisk boxes connect to the PSTN, there is a need to look like an IXC or CLEC. Short of SS7, MF signaling with FGD is the next best thing. I'm woking with Jason Miller, who has sent in other support requests on getting FGD to work. I've examined the source code and it appears that FGD works fine if you connect to a long distance carrier. But, if you "are" the long distance carrier and connect via the LEC's Access Tandem, there's another packet that must be exchanged. We've tried putting it in the dial command and can't get the timing to work since there are additonal winks. Asterisk really looks like an Equal Access End Office at this point. The exchange below illustrates overlap dialing, which is not generally going to happen with Asterisk. Asterisk will have all customer digits and just fake the overlap. Here's what takes place: Customer --> Asterisk --> Access Tandem (LEC) --> IC (long distance carrier) Origionating Sequence Customer dials (10xxxx)+(0/1)+(NPA)+NXX Asterisk Access Tandem IC 1.
