I am a VOIP newbie and Sunrocket refugee. I am trying to use an Innomedia 6328-2RE ATA with the 3cX system and Callcentric VOIP service. I also have an X-Lite softphone and considerring SIP phones. Everything seems to work properly except the analog phone via the ATA cannot dial a 3 digit extension or voicemail. I can dial out and receive calls. I can dial the extension of the analog phone via the softphone just fine. When I try to dial the three digits on the analog phone i get a busy signal. Log files on the 3CX system seem to indicate it's not getting anything at all from the ATA. There are no settings that I can find on the ATA for dialing plans. Any ideas? I am willing to go out and buy a $50 Linksys PAP2 at Compusa is it's just an Innomedia incompatability issue.
