MGCP Caller ID problem

Unanswered Question
Mar 18th, 2009

We just upgrade our callmanager to the version 7.0.2.1000-18 to solve a problem with MGCP.

We are now receiving the Caller id in the gateway but not at the receiving end.

Here is the debug from the gateway

Mar 19 00:19:19.579: ISDN Se0/0/0:23 Q931: TX -> SETUP pd = 8 callref = 0x0001

Bearer Capability i = 0x8090A2

Standard = CCITT

Transfer Capability = Speech

Transfer Mode = Circuit

Transfer Rate = 64 kbit/s

Channel ID i = 0xE9808317

Exclusive, Interface 0, Channel 23

Display i = 'Bell Canada'

Calling Party Number i = 0x0081, '5143436111'

Plan:Unknown, Type:Unknown

Called Party Number i = 0x80, '5147345055'

Plan:Unknown, Type:Unknown

Mar 19 00:19:19.683: ISDN Se0/0/0:23 Q931: RX <- CALL_PROC pd = 8 callref = 0x8001

Channel ID i = 0xA98397

Exclusive, Channel 23

Mar 19 00:19:21.027: ISDN Se0/0/0:23 Q931: RX <- ALERTING pd = 8 callref = 0x8001

Progress Ind i = 0x8088 - In-band info or appropriate now available

Mar 19 00:19:21.387: ISDN Se0/0/0:23 Q931: RX <- CONNECT pd = 8 callref = 0x8001

Mar 19 00:19:21.391: ISDN Se0/0/0:23 Q931: TX -> CONNECT_ACK pd = 8 callref = 0x0001

Mar 19 00:19:33.031: ISDN Se0/0/0:23 Q931: TX -> DISCONNECT pd = 8 callref = 0x0001

Cause i = 0x8090 - Normal call clearing

Mar 19 00:19:33.067: ISDN Se0/0/0:23 Q931: RX <- RELEASE pd = 8 callref = 0x8001

Mar 19 00:19:33.091: ISDN Se0/0/0:23 Q931: TX -> RELEASE_COMP pd = 8 callref

All the possible option are selected in the callmanager.

Does somebody have a idea?

I have this problem too.

That's rough. The Display IE is in there, but it's not showing up on the PSTN.

I would see if you have any old debugs of isdn from your other version, and do a 'stare and compare' on it.

Otherwise, you can try changing the Plan and Type of your calling number, but that's mostly a guessing game.

In North America, usually you must set plan/type as ISDN/national in order for telco to accept your calling number.
