I have been keeping one eye on Linux Telephony for several years now but before i invest what will be a considerable amount of time and money taking a leap of faith i need to know one thing, will asterix support a busy lamp field, ie, is it possible to have an indication on my SIP phone that another phone on the network is busy. I haven’t seen any feature listed or is it assumed that this feature is available
I too have asked that very same question in Australia and have been given a big YES it does provide the DSS/BLF through “HINT” which is a function that forms part of Asterisk.
You can even provide Line assignment which is great…
Just make sure your SIP telephone supports the features … Grandstream 2000 series is what I am investing a lot of time with ; )
