Title: How to set SIP-ALG on my router?
Post by: Mobile1 on February 22, 2016, 08:19:13 am
I have an AT&T Motorola NVG589 router.

The manual is attached.

OBI told me to set the SIP-ALG (session initiation protocol) for voice communication to on.

It seems to use IGMP (Internet Group Management Protocol) to change settings.

Where can I get IGMP software that runs on Windows?

Thank you for your help.

Google is your friend. https://www.google.com/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=IGMP+software+that+runs+on+Windows%3F

Google may be your friend, but it's going to send you down a rat-hole on this one.

There are two mistakes in the original post:  

First mistake:  Obihai should/would have told you to turn SIP-ALG OFF (disable it), not to turn it on, which it is now, by default.

Second mistake:  this has nothing to do with IGMP.  I can't imagine where you got that idea.

This router looks like it was designed by Cisco in the 1990s.  You have to use a command-line interface (CLI) to type commands manually.

To do this, you have to telnet into the router.  So, the software you need is a telnet client.

Use PUTTY (http://www.putty.org/).

See the router's manual, on P. 107 to get started.

See P.118 for the CONFIG command

Once you have a telnet session running, type (without the quotes) "config", press enter, then "set ip alg sip-enable off" and press enter.

Exit out of telnet.

Shop for another router if this doesn't help.

That sounds like the ATT U-Verse Giga-Power router I had when I had that service.  You can NOT use anything else (except perhaps their updated one).

If you can't get in as Steve suggests, let me know, I have some contacts and work in the device management industry and ATT is one of the companies I support).
