Anyone able to use the MGCP feature with asterisk? If so please post your configs and what TA model you use.

Their website contradicts the info from techs relayed in earlier comments. It says:

"What kind of adapter can I use with this service?

You can only use the adapter that is provided by AT&T."

Interstingly, the kit includes a DLink DVG1120 router/firewall/VoIP adaptor based on the little-used MGCP VoIP protocol that has been part of the CallVantage offering since the service launched 6 months ago. Recently, AT&T announced agreements to market its service with SIP-based adaptors manufactured by Linksys, Netgear and Centillion Communications.

Can you disable CallVantage's voicemail? We'd rather just use our machine... Thanks!

1. 30 DAY TRIAL, THEN ONE YEAR COMMITMENT. $59 early term fee.

2. Customer Service says the subsection of the agreement capping minutes at 5000 even on the unlimited plan has been deleted.

3. Virtual numbers now supported @ ~$6/mo per.

4. AT&T second level techs confirm that they will allow (but not support) any use of the TA from within your LAN (or WAN, I suppose) that you can make work. This includes a bridge to MDGC for terminating calls upstream through the callvantage TA to PSTN. If you can support this, possibly through Asterisk, AT&T does not have a problem with you playing 'Personal Telco.' I told them I wanted to terminate calls from my PocketPC over GPRS or WiFi using a softphone, and they didn't blink an eye.

5. Confirmed that NAT is now supported. There are differences of opinion regarding whether to put the TA behind or in front of the router. From browsing forums, some people seem to prefer keeping the TA in front, using a switch or 'front router' with QoS features to manage the bandwidth of each network segment. YMMV.

6. Equipment will ship next bus. day after order, and arrive in approx. 5 days in most of US. The service will go live approx 2 days later.

7. RE on the DLINK router offered by AT&T is good enough for 5 phones on each jack, according to 2nd lev. tech. (But they may have meant five, total. The rep was unclear on the concept). They will not give the exact specification, which they claim is proprietary. (?!?)

1. Service works with NAT (TA can be behind a NAT router)
2. Price reduced to $29/month

1. More area codes available now
2. Price reduced to $34.99/month
3. Caller ID w/Name now sent to phones and saved in Call Log
