I am new to Asterisk and I'm setting up my first Asterisk box. When
recieving inbound SIP calls from sipphone.com my friends would not get
the ringing indicator after I did an answer command. I found that
after playing a gsm file first the ringing started to work like it did
for my pots incoming calls. I created a short virtually silent gsm file
and that worked as well if played before the dial command. Just
wondering why SIP works this way and if there is a better solution.
BTW, I'm not using the "r" parameter to the dial command.
