Hi ALL

im struggling getting some SIP dialups going. sometimes they work, but most often they dont.

for example....

I have two USR 56k Sportsters on a grandstream SIP thingy,

one minute i'll connect fine and then the next time i get something
like the following:

CONNECT 24000/V34/NONE
�]�C �s

**** BUNCH OF OTHER GARBAGE TILL I HANG UP **

other times it will work and i get to the login prompt and it will just "hang"

i've even just tried tying minicom to mini com as far as software goes, and it's the same.

i'm sure it has something to do with either the init strings or (most likely) the grandstream.

i'm just at a loss. I havent figured out a way to force a specific DTE speed (57k6 or 115k2) and also a way to force it not to do compression
or error correction. Ideally i want to be able to have a max connect at 57600 and no v92, v44 et al

anyone got any thoughts (other than pay for a bunch of real pots lines) LOL

regards

Charles Blackburn

Hi Charles,

Did you ever get your USR 56k to connect via your SIP setup?

I'm looking for info how to get my modems to connect togther.

I have a cisco ata spa122 and I'm using asterisk and freepbx (front end).
I have two extensions and they each can call and detect rings but never connect.

I'm using pjsip (not legacy).

Someone has to have found the solution to this issue with modems over a VOIP system.

.. The only place I want data loss is on my credit card!
