I am new to VOIP and TENOR product and have several question about them.
1) What does PACKET SAVING option on TENOR exactly do? Is it nessecary or not? Without it , what is the required bandwidth for each phone line?
2)What is the minimum number of valid IP addresses needed to stablish a VOIP service for prepaid phone calls?
3)Which billing software is more suitable and cost effective?
4) Does Qbill software work with Cisco as well as TENOR?
Any hints would be appreciated
