[asterisk-users] Dragging the dialup customers along, possible?
We have an Ascend Max router that has a PRI plugged into it, providing our current dialup users with web access. The PRI is no longer cost effective, so I've been tasked with converting it to something cheaper. We added a DID to our (existing) asterisk system (we have a couple dozen voip customers). We added an Adtran 908 to convert the VoIP signal into a virtual PRI for our MAX router to handle dialup calls. When dialing into the number with a modem, MAX sees the call, picks up and apparently tries to negotiate it, but eventually disconnects. It HAS, however, twice, successfully connected the call for a short time, but no browsing was possible. I've done some debugging output on the Adtran which seems to indicate that an RTP BYE command is received: TM.T01 01 SipTM_Connected rcvd SIP call-leg request: BYE ... This is the first difference between a debug output where the call connected and one that does not work. This is the one that doesn't work. TL;DR - Is it possible to do dial-up through Asterisk? Or is it like t38 faxing that is 'possible' to get working, but not if you have other job responsibilities?

Re: [asterisk-users] Dragging the dialup customers along, possible?
It is possible to use Asterisk as a dialup PPP server, but only if you are doing PRI between the telco and Asterisk (see core show application DAHDIRAS). You could bring analog POTS lines into a dialup server (Portmaster maybe?) if PRI is too expensive. Can outsource your dialup customers to a national network? You could simply stop providing dialup service. -Original Message- From: asterisk-users-boun...@lists.digium.com [mailto:asterisk-users-boun...@lists.digium.com] On Behalf Of C F Sent: Monday, August 29, 2011 4:18 PM To: t...@ewebforce.net; Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [asterisk-users] Dragging the dialup customers along, possible?
