Hello,
I configured my dial-peer in this way:
dial-peer voice 1400 pots
voice cut-through alert
preference 4
destination-pattern 199151119
progress_ind setup enable 1
no digit-strip
port 0/0/1:15
!
Now i see the PI reminder:
Nov 15 14:39:07.121 CET: ISDN Se0/1/0:15 Q931: TX -> SETUP pd = 8 callref
= 0x1C5C
Bearer Capability i = 0x8090A3
Standard = CCITT
Transfer Capability = Speech
Transfer Mode = Circuit
Transfer Rate = 64 kbit/s
Channel ID i = 0xA9839F
Exclusive, Channel 31
Progress Ind i = 0x8181 - Call not end-to-end ISDN, may have in-band
info
Calling Party Number i = 0x0180, '03631970353'
Plan:ISDN, Type:Unknown
Called Party Number i = 0x81, '199151119'
Plan:ISDN, Type:Unknown
Nov 15 14:39:07.133 CET: ISDN Se0/1/0:15 Q931: RX <- SETUP_ACK pd = 8
callref = 0x9C5C
Channel ID i = 0xA9839F
Exclusive, Channel 31
Nov 15 14:39:08.253 CET: ISDN Se0/1/0:15 Q931: RX <- CALL_PROC pd = 8
callref = 0x9C5C
Looking at this:
http://www.cisco.com/en/US/tech/tk1077/technologies_tech_note09186a0080094c33.shtml#progresstones
I would expect the call to be cutted-throug after the SETUP_ACK has been
received.
Anyway I have the same problem, no audio i sent to my phone before the
CONNECT message.
Thank You
