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.
