[Asterisk-Users] DID trunk suggestions for Asterisk

[Leslie Chan]

Hi Steve,

I posted a similar requirement to Digium and they confirmed that TDM400P
does not support DID on analog trunk.

Am I missing something in between?

Hi,

Unfortunately, we do not support DID on analog lines.

In the event that we did, the TDM02B would be sufficient to provide
two FXO ports and you could hang IP phones out on your LAN.

Cheers.

Hi Joe,

In hardware terms a TDM400P does what you need. I don't know if anyone
has implemented the software support for using it in this way, though.

Steve
