I have an ESI 200 system with SIP 8 card installed. Here is the problem I am having, I am unable to make any outgoing calls, I get a dial tone but no action after dialing a number. I am able to receive calls on my DID numbers with no issues. Also the SIP provider says they are not receiving anything on there side being sent from the phone system. Any help would be greatly appreciated been working on this for about three weeks now.

I got it working, but is dropping outgoing voice during a call but not all the time. Had anyone experienced this issue?

What does ESI Tech Support say? If it was me I would get my SIP trunks through them just to avoid any finger pointing.
