All,<br>I am trying to get an alarm system which calls a central monitoring center to work via FreeSwitch. I am using a Linksys SPA-1001 and a SIP trunk (Vitelity). Even though the call is answered the "modems" never connect, from what I can tell. I see the call being answered in Freeswtich, but the alarm system reports a "comm error". PCMU is being used for the call and it does hang-up with "NORMAL_CLEARING".<br>
<br>Does anyone have any ideas how to get "modems" to work over VoIP? Any suggestions would be appreciated.<br><br>Thanks<br>Kubes<br><br>
