H.323-trunk -> works, but no function if an extension is forwarded

Hello community,

i´ve set up a trunk between two UC500 with H.323.

Everything works fine, extensions are translated with correct node-numbers and so on,

calls are possible and missed calls can be answered correctly.

But if anyone calls over the trunk an extension which is forwarded (no matter: all, busy or noan to VoiceMail or to an other extension)

it doesn´t work; the A-side is disconnected immediately or after the noan-timer.

But if I call an free extension on side B and this extension makes a call transfer to an forwarded extension,

then it will work and I get the VoiceMail-Announcement on the side A.

The only hint with deb voice ccapi error

000147: Mar 11 11:48:45.235: //-1/xxxxxxxxxxxx/CCAPI/cc_validate_mlpp_info:
   Unsupported MLPP Service Domain Network 0

From internal extensions or PSTN does it work with call forwarding.

What kind of phone lines do you have?  If you have a SIP trunk,  The provider possibly doesn't like the SIP diversion header.

Regards

Adam Compton

Hi,

at each UC there are two ISDN-lines from the PSTN

and the trunk/link between the UCs is within an MPLS-cloud.

(in the moment the MPLS-coud is represented by a CISCO 1712)

No SIP ...

Kind regards, DetNit

hmmm. interesting....

I wonder if registering a transcoder or MTP resource would make any difference.  Of course. this is well beyond CCA configuration, but it looks like you did the dial-peers manually.

Adam Compton

Hi Adam,

this is right - no CCA used for this configuration.

The CLI is my buddy and I took some configuration guidelines from the CME.

I´m confused about this dysfunction and have no further ideas.

Kind regards,

DetNit

A transcoder is always worth a shot.  Here is the configuration guide for transcoder on CME:

http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/admin/configuration/guide/cmetrnsc.html

basically looks like this

sccp local vlan1

sccp ccm 10.1.1.1 id 1 priority 1 version (5.0 or above).

sccp

sccp ccm group 1

associate ccm 1 pri 1

associate profile 1 reg uc500xcode

dspfarm profile 1 transcode

codec g711u

codec g711a

codec g729r

codec g729br

max sessions 5

associate application sccp

no shut

telephony-service

sdspfarm units 1

sdspfarm transcode 5

sdspfarm tag 1 uc500xcode

This is just an example and would need to be altered to match your system.  I figured i would would type something up for you real quick

Adam Compton

Hi DetNit,

Before you apply that Config can you check please to see if you have enough DSP resources to do it? I have seen machines go bad when applying the config and there was not enough resources for it.

ROUTER# sh dspfarm all

And it should look something similar to this:

Dspfarm Profile Configuration

Profile ID = 3, Service = TRANSCODING, Resource ID = 1 

Profile Description : Transcoding when conferencing is enabled

Profile Service Mode : Non Secure

Profile Admin State : UP

Profile Operation State : ACTIVE IN PROGRESS

Application : SCCP   Status : ASSOCIATION IN PROGRESS

Resource Provider : FLEX_DSPRM   Status : UP

Number of Resource Configured : 1

Number of Resource Available : 1

Codec Configuration

Codec : g711ulaw, Maximum Packetization Period : 30

Codec : g711alaw, Maximum Packetization Period : 30

Codec : g729ar8, Maximum Packetization Period : 60

Codec : g729abr8, Maximum Packetization Period : 60

Codec : g729r8, Maximum Packetization Period : 60

Dspfarm Profile Configuration

Profile ID = 1, Service = CONFERENCING, Resource ID = 2 

Profile Description : Conferencing profile

Profile Service Mode : Non Secure

It is important to know what you have available before you make any configuration changes... OH and please please please make a backup of your config before you make the changes, and put that backup on the flash memory, even if you do not commit the changes.

Cheers,

David.

Hi David,

thank you for this information.

Below the output, it´s identical on the second UC.


MOSKAU_VOIP1#sh dspfarm all
DSPFARM Configuration Information:
Admin State: DOWN, Oper Status: DOWN - Cause code: ADMIN_STATE_DOWN
Transcoding Sessions: 0(Avail: 0), Conferencing Sessions: 0 (Avail: 0)
Trans sessions for mixed-mode conf: 0 (Avail: 0), RTP Timeout: 600
Connection check interval 600 Codec G729 VAD: ENABLED

Total number of active session(s) 0, and connection(s) 0


Total number of DSPFARM DSP channel(s) 0

MOSKAU_VOIP1#

and if I try this I get following answer

MOSKAU_VOIP1(config)#dspfarm profile 1 transcode universal


Dspfarm profile 1 :: No resource, check voice card or dspfarm service is not configured
MOSKAU_VOIP1(config-dspfarm-profile)#

How can I setup this resources?

Kind regards,

DetNit

I forgot to add this because it is normally setup on a uc500:

voice-card 0

dsp service dspfarm

You should be able to program a dspfarm profile.

Adam Compton

Hi Adam,

I´ve done this configuration


voice-card 0

dsp service dspfarm

but I´m not able to give a maximum session > 0

and so I can´t make a no shut, because it´s need a value >0

Kind regards,

DetNit

You might have maxed out your dsps.  What kind of UC500 do you have?

The models are UC520-8U-2BRI-K9 V02 and UC520-32U-4BRI-K9 V02

you might be out of dsps to do that then...

Hi DetNit,

I would really love to log into your system (Via SSH) and have a look at this, even based on it being a 2 BRI or even a 4 BRI system you should still have enough DSP resources to at least do minimal conferencing.

Something is not right and I would really love to investigate this further.

Cheers,

David.

Hi,

i took the config and put it on a UC540W-BRI-K9 and the behaviour is the same.

I put the config from Adam on the box and I was able to set a maximum-connection value, but nothing changed.

No informaton with several "deb dsp..."-commands

I think that is not a problem of not enough DSPs ...

The only information with deb voice ccapi error on incomig calls

(but what´s the meaning of this?)

SHIT! (sorry for this ...)
