Dear Experts, Yet another newbie thread, seeking your help. need to know few things for the regular day to day maintenance of Elastix. My Elastix box is almost ready to go into production with Digium TE212P Card for E1 (100 DID) 2 analog fax machines, Avantfax, Aastra IP Phones for total of 40 Extensions and customized IVR. 1. what are the regular maintenance requirements for Elastix machine such as reducing the logs or deleting the logs on daily basis or weekly basis? in order to keep the Hard Drive Space always available for recordings and Voice Mails Etc. 2. for the queue periodic anouncements i want to change default sound files is that ok? or would it cause a mess? 3. User Portals, as i heard that Elastix allows users to have their own portal for things like voice mail customization, changing password etc? how do i create that? 4. Voice Mail Unavailable or Busy message resides in which directory? i tried to search but i couldnt find as i want to change it with professionally recorded greetings. 5. Connecting 2 Elastix Boxes together (both in diffrent countries) what are the best practises? Using Public IP or setting up VPN? if VPN which is best Hamachi or Open VPN? any pointers for the setup guide? As you all knew im a newbie and have just started with telephony and linux in general but have learnt few things from you and other communities, again expecting great response as always. Thank You All.
