| sure, it doesn't need to upgrade your pbx if your needs does not involve slot expansion.
I also agree with you tha the upgrade cost is too high relatively your company's needs. but you cant avoid the upgrade when the siemens communication company upgrades their software products callscan,ringmaster...3 times a year.In this case you have to upgrade from cpu V.6 to V.8.
When you send worked on the ISDX you mean progamming them? |
