Hello,
I have the "no ringback tone" problem when I call from a SIP softphone
(Linphone)
to the PSTN (through a cisco 5300 with PRI connection to telco).
Linphone --> SER --> c5300 --> POTS
My conf on c5300:-
!
dial-peer voice 1001 pots
destination-pattern 210.......
no digit-strip
port 0:D
!
I used also the following commands on pots dial-peer with no success.
progress_ind setup enable 3
progress_ind connect enable 8
any ideas ?
thank you,
Kostas
