Suggestion for VoIP gateway to work with Asterisk


I am studying for a large/distributed Asterisk installation.

From the forum postings and Google I found out that I can use
VoIP gateways like Cisco, Audiocodes or Quintum together with Asterisk.

I would like to know if someone has integrated these products with Asterisk server successfully and if someone can recommned one over the other products.

I am going to connect 24 FXOs to one gateway and reliability is much more important than price.


We already tried * with E1 cards connected to Cisco AS5300 4E1 - no problems at all.
