[asterisk-users] Asterisk + Cisco Call Manager

[Timothy Smith]

Hi David,

We're migrating from Cisco to asterisk because cisco is expensive to
maintain, besides we can achieve more with asterisk like customised
IVRs etc.

This being a large production environment, we can't just change over
without testing thoroughly..it has to be down in phases such that
theye's no downtime at all. Now, for outgoing calls,  the cisco
gateways are working in parallel with asterisk. Now, i'd like to
completely get rid of the cisco gateways by routing incoming calls
through asterisk too (to the call manager, and finally the phones).
After that, they'll be satisfied and i'll start registering the phones
to asterisk until everything is asterisk. It has to be a smooth
transition, just fyi, we're about 200 employees.

I'll appreciate any advice towards achieving this.

Kind Regards,
Wison
