[asterisk-ss7] Asterisk 1.8.4.2 + LibSS7 1.0.2 : Early Media Problem

[Nyamul Hassan]

Thank you, Konstantin for your prompt reply.  However, I am a bit confused
after reading your email.

The calls are coming into Asterisk over SIP and going out on TE420P cards
towards Telco using SS7.  Using Chan_SS7, we can hear the RBT (ring back
tone) from the Telco.  But, on LibSS7, we are not hearing anything at all,
unless we set "progressinband=yes" which makes Asterisk generate fake ring
tones, and that works, but not ideal.

So, your mention of "first" and "second" is being a confusing for us.  Sorry
for being an inconvenience.

Regards
HASSAN
