[asterisk-biz] Question about legacy PBX with Asterisk

[Miguel Fernandez]

We are studying to offer as solution for a customer a legacy central PBX
(Avaya) and use in remote offices Asterisk PBX.

We are studying how to connect PBX using IP. We have fund a lot of
references of H.323 integrations. We would want to know if there is any
experience in integrating both PBX using SIP protocol (using the Avaya Sip
Server).

Regards,

Miguel Fernandez
