I know a hotel client with at most 250 rooms. They currently have less than 300 telephone extensions using Avaya SIP phones connecting all their departments to an Avaya PABX which caters all their telephony operations.
Now, they’re planning to literally replace the Avaya PABX server system, but preserving the Avaya SIP phones, with an Asterisk PABX server. I read an article that Avaya SIP phones are very compatible with Asterisk. So, no problem there. However, what keeps me challenged is their PMS. They are using MICROS-Fidelio’s Opera as their PMS.
My concern, is would Opera be compatible with Asterisk? What would happen to the database if it is integrated with Asterisk? Opera is DOS-based, if this would matter.
Any help would be greatly appreciated.
