I've gotten asterisk running fine with several Grandstream phones as well as linphone on my PC. Now the last step is configuring the multitech MVP 130s that I have to send outbound calls to the POTS lines attached to the MVP130s. I'm having issues with the outbound and inbound telephone book entries I believe. The multitechs work fine when configured to talk to each other at remote locations, but getting them to accept a call from asterisk hasn't worked well. I've configured them in sip.conf and made a simple entry in extensions.conf to send an outbound call to the first MVP130 but I always get 404 on it. Does anyone have a multitech MVP unit working configured as an FXO talking to asterisk? I'd really be interested in the settings you used in the multitech. Thanks, Dean
