Hold, Transfer and other functions unavailable to end-user

A short description of the setup:

One centralized CCM Cluster (4.1.3)

Five regoins/locations/pools.

All locations are set to use g711 internally and across WAN.

Now to the problem at hand:

External Calls to any phone in a remote office (this office has it's own 2800 GW, and PRI) is impossible to put on hold, transfer or anything other than terminat. If the user presses "hold" the connection is partially lost. The caller and called party can no longer talk/hear each other. The call is still "active" in the phone display, but the only thing to do is to end the call (At which point the called party releases the call, but the gw does not release the incoming call until 10 seconds later).

Here is a isdn q931 trace of a call:

*Aug 3 12:35:26.415: ISDN Se0/0/0:15 Q931: RX <- SETUP pd = 8 callref = 0x00CC

Sending Complete

Bearer Capability i = 0x8090A3

Standard = CCITT

Transer Capability = Speech

Transfer Mode = Circuit

Transfer Rate = 64 kbit/s

Channel ID i = 0xA18394

Preferred, Channel 20

Calling Party Number i = 0x1183, 'XXXX'

Plan:ISDN, Type:International

Called Party Number i = 0xA1, 'XXXX'

Plan:ISDN, Type:National

*Aug 3 12:35:26.427: ISDN Se0/0/0:15 Q931: TX -> CALL_PROC pd = 8 callref = 0x80CC

Channel ID i = 0xA98394

Exclusive, Channel 20

*Aug 3 12:35:26.611: ISDN Se0/0/0:15 Q931: TX -> ALERTING pd = 8 callref = 0x80CC

*Aug 3 12:35:28.479: ISDN Se0/0/0:15 Q931: TX -> CONNECT pd = 8 callref = 0x80CC

*Aug 3 12:35:28.587: ISDN Se0/0/0:15 Q931: RX <- CONNECT_ACK pd = 8 callref = 0x00CC

*Aug 3 12:35:34.587: %ISDN-6-CONNECT: Interface Serial0/0/0:19 is now connected to 4721550000 unknown

*Aug 3 12:35:36.115: ICT ver in h323_gw_dialpeer.c 1

*Aug 3 12:45:34.775: %ISDN-6-DISCONNECT: Interface Serial0/0/0:19 disconnected from XXXX , call lasted 606 seconds

*Aug 3 12:45:34.775: ISDN Se0/0/0:15 Q931: TX -> DISCONNECT pd = 8 callref = 0x80CC

Cause i = 0x8090 - Normal call clearing

*Aug 3 12:45:34.827: ISDN Se0/0/0:15 Q931: RX <- RELEASE pd = 8 callref = 0x00CC

*Aug 3 12:45:34.827: ISDN Se0/0/0:15 Q931: TX -> RELEASE_COMP pd = 8 callref = 0x80CC

The ccm trace is in the attached file

I see the "error": StationCdpc - ERROR active10: hold rejection|

But have no idea why, and what to do with it. And why does this error cause a "freeze" to the call in progress? The call is "lost", and terminating is the only solution.

The really strange part is this:

The situation described above is true for all external call to this one location if the the call in progress has lasted 3 minutes+++. If a call in progress is less than 3 minutes old, all functions are operational as the should be. Internal calls to the same location do not behave as described above. Nor any external call to any other location (centralized or remote).

Help apreciated

Re: Hold, Transfer and other functions unavailable to end-user

You need to use a media termination point (mtp). Select "Media Termination Point Required" in the gateway config and make sure an mtp is available to use.

Thank You!

That was all there was to it.

But here is the thing I do not understand: Why does the problem only occur if the conversation is 3-4 minutus or older?

Re: Hold, Transfer and other functions unavailable to end-user

Hi there we have the same error,

it's a message from the stationCdpc,

Cisco CallManagerStationD: (0001818) restart0_DStopInd: No Linked StationCdpc

and the call is not completed!, sometimes it goes tru but sometimes it gets dropped and we receive this message....

Do you have an idea?
