Depending on what the link looks like to the computer, you very well might be able to use TDMoE to do what you are looking for. -A. ___ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

I can appreciate the desire to avoid reconfiguring existing hardware, but that is part and parcel of what we are discussing: reconfiguring hardware. Without further specification, it has no bearing on how to preserve application behavior, which is what we are trying to accomplish with this discussion. I don't wish to second-guess your analysis of the business requirements - you are the authority - but your initial post expressed a desire to move toward an Asterisk configuration as one of your goals. Toward that end, development of an appropriate dialing plan ultimately must happen, and I would think if done properly, would not change dialing patterns or extension numbering unless this is what you desired. I must agree that fax and modem performance is problematic, but here again, this would be an issue anyway when you transition completely to Asterisk, as you implied about your long-term plan. So perhaps now is the time to address this matter. Are you sure you really want to do this at all?

Bill, The question has been answered; Asterisk is NOT capable of providing a clear PTP TDM path between two boxes configured with t1 cards and any type of trunking. I am aware of my other options, and will move forward with the knowledge that a solution we have implemented with back to back Cisco routers in the past is not possible with asterisk. I do intend to move forward with asterisk in this particular environment, but I wish to integrate asterisk by placing it between the telco PRI and the primary Nortel switch, not between the primary switch and a branch office on a T1 tie trunk. I will leave the leased PTP t1 in place for now since it cannot be dropped without significant additional work for a temporary situation. BTW, I did learn that the RAD IPMux-11 will do exactly what we need, but cost is about $1500/pair, so the break even on a $300/mo leased line is 5 months, in which time we are not planning to need the T1 anymore. With that said, it is still about $6k less than the Cisco solution. Thanks for your support on this. -Original Message- From: [EMAIL PROTECTED] [mailto:asterisk-users- [EMAIL PROTECTED] On Behalf Of Bill Michaelson Sent: Thursday, January 26, 2006 12:29 PM To: asterisk-users@lists.digium.com Subject: [Asterisk-Users] Re: * point to point t1 solution? / alternatives I can appreciate the desire to avoid reconfiguring existing hardware, but that is part and parcel of what we are discussing: reconfiguring hardware.

Toward that end, development of an appropriate dialing plan ultimately must happen, and I would think if done properly, would not change dialing patterns or extension numbering unless this is what you desired. Exactly what I was thinking. If Asterisk is to replace the nortel hardware some day, it does need to be doing some signaling. Plus, on a stable 10ms link, faxes should be really no big deal (providing you use ulaw / alaw)... I must agree that fax and modem performance is problematic, but here again, this would be an issue anyway when you transition completely to Asterisk, as you implied about your long-term plan. So perhaps now is the time to address this matter. In a way it sucks that Asterisk doesn't support modem over ip type data, but on the other hand: Doing a analog (piece of paper) - digital (scanning process) - analog (modulation over TDM) - digital (conversion to TDMoIP) - analog (demodulating on the other fax) - digital (reconstructing the image in fax memory) - analog (printing) conversion doesn't make any kind of sense... It might be great for legacy systems, but it's so not the right way of doing it.
