Thinking out loud. Helps me and may trigger something for you.<br>
<br>
Unity Connection sends MWI message to CUCM. I *think* CUCM
initiates a call from the MWI Off number. It *should* use the CSS
of the MWI Off DN. <br>
Q1: In DNA how does a call route using the CSS assigned to the MWI
Off Number?<br>
<br>
I'm 100% clear on the SIP MWI implementation so it could use the CM
service parameter "Message Waiting Indicator Inbound Calling Search
Space". <br>
Q2: What is configured here?<br>
Q3: Test this CSS in DNA?<br>
<br>
<br>
It should be possible to get a bit of clarification on what is
happening. In Q.SIG MWI is a call to the DN with special bearer
capability and facility APDU). <br>
<br>
Feb 18 16:44:33.610 CST: ISDN Se1/0:23 Q931: RX <- SETUP pd = 8
<br>
callref = 0x1201<br>
Sending Complete<br>
Bearer Capability i = 0xA880<br>
Standard = ISO/IEC<br>
Transer Capability = Unrestricted Digital<br>
Transfer Mode = Circuit<br>
Transfer Rate = Packet - not specified<br>
Channel ID i = 0xAC<br>
Facility i =
0x9FAA068001008201008B0102A12402020D00020151301BA5090A0104120438383032<br>

Calling Party Number i = 0xC9, '3100'<br>
Plan:Private, Type:Subscriber(local)<br>
Called Party Number i = 0xC9, '8802'<br>
Plan:Private, Type:Subscriber(local)<br>
<br>
Using raw data as an example:<br>
0x9FAA06800100820100A20B02020D0030050201510500<br>
Starting from A2(APDU type):<br>
A2 Rose = Return result<br>
0B length = 11<br>
02 integer<br>
02 length = 2<br>
0D 13*256<br>
00<br>
30 SEQUENCE<br>
05 length = 5<br>
02 integer<br>
01 length = 1<br>
51 Operatin value = 81 (MWI OFF)<br>
If the operation value is 80, then it is for MWI ON.<br>
<br>
<br>
The important thing for you is the nature of the call - it is a call
with the called party set to the line that should set (or clear)
MWI. Either read the CM SDI traces looking for this call or enable
CDR for zero duration calls and check CDR's to see if this call is
being attempted and what is happening to it.<br>
<br>
If you cannot find a call to the affected DN then it's failing in UC
or in the UC to CUCM integration.<br>
<br>
Hope this helps,<br>
Wes<br>
