Just commenting on the voip stuff, option 2 will work and depending on the PBX you will be able to use all your features. The features will work only if you can pass the signalling info' between the sites so it depends on exactly how the pbx does it, I know that for example it works between two Meridian PBXs where the d channel, 16, was passed between two AS5300s (you can use 2600 or 3600s). Some PBXs use other channels as well for features and this is where problems with voip occur so you'll have to test it, cheers wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > hi. > > i have 3 offices in different cities. > all of offices has ericsson md 110 pbx. > i want to connect these pbxs. > i know i have some choices. > > Choice 1) i will get 2Mbps PRI leased lines between pbxs.
