Hi Humberto,

We had this problem with calls being sent to a PRI. The two ringtones were
due to both an RTP audio stream being generated from the PRI (this is the
one we wanted) and also a SIP 180 ringing response being sent by the same
Asterisk server. I'm not sure why both are getting sent, in 1.0.7 I'm pretty
sure they weren't. The fix was simply to set progressinband=no in sip.conf
on the Asterisk server with the PRI.

The reason you only get the doble ring on one UA and not others seems to be
entirely down to the UA. In our case the Linksys units act passed on both
ringing indications where as Cisco IP Phones disregarded the SIP 180 and
just passed on the RTP.

Hth.
