hi list
need your opinion. thanks in advance
when calls come in from zap channel (te110p as E1/PRI) and go out to a SIP
peer, no ringtone heard at zap channel.
sip.conf:
[from_sipproxy]
progressinband=no
type=peer
context=from-proxy
host=xxx.yyy.zzz.www
port=5060
disallow=all
allow=alaw
extensions.conf
[pri]
exten => _X.,1,Dial(SIP/[EMAIL PROTECTED],,r)
whether using option r in Dial command or not makes no diference.
calls from sip to zap channel work well.
i traced sip packets, found that sip device did send "180 Ringing".
it looks like asterisk tells zap channel to say "there's inband information"
but not to generate ringtone.
on * console, "pri debug span 1" shows
