I m a phoner user [not lite] and i have the following problems:
1. Is there a way to export my phonebook contacts? Or at least backup them since i have more than 500 and i am afraid that i could loose them. I cant find any file in my installation with the data. 
2. I use phoner with a grandstream pbx. It seems i cant send dtmf tones (such as #72 for example) with phoner in order to use some features of my pbx. (pbx setup is ok since other clients succefully can send these codes to the pbx).
Thank you!

You cant imagine how much i love your software. I do use lite version as well and im aware that phoner "classic" is not supported any more but i do use it cause of the answering machine. i do have a "sophisticated" pbx but since during working hours its difficult for me to answer the phone (and i have more than 50 missed calls per day) this feature really fits my needs since its very fast and easy to use and i can see in one window what is happening.
I found the file that you mentioned. Thank you for your help!
