Sip.conf and extensions.conf configuration for Exchange 2010 U.M.

Report
Question

Hi All, I'm using Exchange as our voicemail system. Everything works fine until the
1 week mark when Exchange changes the port number used, then Asterisk 1.8
seg faults and I have no phones (unless I restart the U.M. service before
the 1 week period is up). Since that is a hack, I'm hoping someone can post
their working configs that accomodates the port change. The documentation
I've seen is still a little unclear to me. I'm not using secured mode, so
just using ports 5065/5067. Thanks for your help. Jim

Require suggestions - GSM Gateway Asterisk

Report
Question


Hello,
I am looking for ideas and suggestions. I want to use a 16 port GSM gateway as a trunk for outbound/inbound. I will also have two PSTN phone lines coming into the Asterisk server. All calls will go to an IVR on the Asterisk PBX. Outbound from extensions will route to GSM-GW when the dialed number matches a pattern set in the GSM-GW trunk. And accordingly for the PSTN trunks. But that's not the problem. The problem is that this GSM-GW (Eurotech VoIP2All 16 channel gateway) doesn't handle SMS properly. It supports Email-to-SMS (that too, only…

FXS - Power Alarms

Report
Question

Greetings- On occasion, I'm seeing the following in syslog on some systems using analog cards with FXS modules: [ 1664.861183] Power alarm on module 1, resetting! These are typically cleared by restarting asterisk/dahdi, or power cycling the system. However, I'm wondering if anyone can explain what condition exactly causes this. My best guesses: -Too high current draw on port (shorted pair)
-Not enough current supplying card/module (bad power supply)
-Voltage introduced to FXS port (FXS port connected to FXO or POTS line for example) Thanks!

T.38 "client" for Linux?

Report
Question

I am looking for a simple way to send occasional faxes via the FXO
port on my SPA3102 -- without having to connect a fax modem to an
ATA. In an ideal world, this would be some sort of "softfax" that
runs on my Linux desktop and talks (via Asterisk) to the SPA3102 with
T.38. This is one of those things that I thought would be relatively
straightforward, but a couple of hours of Googling has left my head
spinning. I'm posting here in the hope that there is a (fairly) simple way to

The image you provided didn't open so I'm not sure about the design. If you

ISDN2 PCIe Card for Asterisk

Report
Question

what do you mean exactly?! One what?! What do you plan to accomplish?! Do you mean a 1 Port ISDN BRI Board?! Difficult to find, and thus boards
are really expensive, not under 400.- € inkluding DSP Processors.
I advise you taking Gentoo Linux, getting asterisk on it and put a
single Port HFC-S PCI (not PCIe) Board in your CPU. If you need something really professional, for Serverside, I advise you
sangoma.
