Called# column is blank with IOS Command "show voice call status"

[alexandre.ratel]

Somebody can say me why the Called# column is blank when I'm using the IOS command "show voice call status" ?

For exemple :

#sh voice call status      
CallID     CID  ccVdb      Port        Slot/DSP:Ch  Called #   Codec    MLPP Dial-peers
0x29C6     267B 0x191C6364 0/1/0:15.8       0/1:4  *           g711ulaw 0/0
0x29C8     267C 0x02311588 0/0/0:15.29      0/1:5  *           g711ulaw 0/0
0x2A58     26C4 0x191C6364 0/1/0:15.11      0/1:7  *           g711ulaw 0/0
0x2A5A     26C5 0x02311588 0/0/0:15.28      0/1:15 *           g711ulaw 0/0
0x2B0C     271B 0x02311588 0/0/0:15.31      0/1:1  *           g711ulaw 0/0
0x2B0E     271C 0x191C6364 0/1/0:15.24      0/1:2  *           g711ulaw 0/0
0x2B10     271D 0x02311588 0/0/0:15.30      0/1:3  *           g711ulaw 0/0
0x2B12     271E 0x02311588 0/0/0:15.27      0/1:6  *           g711ulaw 0/0
8 active calls found

It's not realy blank but just a star and not the called number.

Alexandre,

Is this an MGCP gateway?

[alexandre.ratel]

Yes this is an MGCP gateway

Alexandre,

The show voice commands are written for use when the gateway  controls the call via SIP/H.323 and don't get much information when CUCM  controls the call via MGCP.  What you are seeing is what the voice subsystem in the router knows about a call from a L1 / L2 perspective.  CLID is Layer 3.

If you want to see if a particular call is going out correctly you can watch the output of debug isdn q931.

Steven,

I'm curious about this answer. You see I am seeing the configuration of the same router (MGCP gateway) from Version 15.0(1)M4 where I can see the Called # there and then from Version 15.3(3)M3 where I can see the Called # as *.

So is your answer conditional to certain versions of the IOS?

MGCP and SCCP don't provider called/calling party information to the router since the dialplan/call routing is handled on the CA.  Hence that output won't contain the information, since the router is unaware of the calling/called numbers.

You need to use SIP or H323 if you want those fields to populate.

Thanks a lot, I didn't know this point
