Hi all,
have a little problem while holding an internal call between fxs ports.
Normally I have defined a MOH which can be heard on external calls, between IP-Phones and on IP-Phones when an analog device holds the call.
If an analog device holds another analog device or an IP-Phone (connected to an analog device) holds an analog device you can´t hear the MOH.
What can be the reason?
Thanks Stefan

Hi Stefan,
I have never seen anyone do this before, this as got my interest peaked
Can you tell me what are the analogue end points, and how you are doing it I.E the procedure or the FAC that is being used.
I would like to work this up on my 560 and see if I get the same result.
Cheers,
David.

Hi David,
I´m using simple DECT cordless phones, which have an analog connected base station.
To hold a call I just press the "R" Button (Flash).
Important is that you have set max-calls-per-button 2 on the phone.
You can also transfer calls when you press "R" dial another extension and hang up.
Or you can make a conference call when you press "R" again, when connected to the second extension.
Perhaps you have to set flash-timing on the analog port and the end device ( port has to be higher than the device)
otherwise nothing happens or the first call will be disconnected.

Hi Stefan,
Thank you very much for this, will now go on the hunt for some cordless phones and see if I can reproduce this myself
Cheers,
David.

Hi Stefan,
I ended up having to use just normal analogue phones, and was not able to reproduce the issue, I am not entirely sure what is happening at your end though... Is this system configured using CCA?
Also has this worked in the past?
Cheers,
David.

Hi David,
9 Months have passed and I had no further time to work on this problem.
Regarding your questions:
1. The system is initialy configured by CCA and afterwards troubleshooted via CLI, because I´m using it in Germany.
2. It has never worked.

Do you have configured a transcoding farm for the DSPs?

Hi Christian,
I didn´t find anything in the current configuration.
Can you tell me, which parameters have to be set?
It´s a UC540.
Thanks Stefan

Try this:
dspfarm profile 3 transcode universal
codec g711ulaw
codec g711alaw
codec g729abr8
codec g729ar8
codec g729r8
codec g729br8
maximum sessions 2
associate application SCCP
!
telephony-service
sdspfarm units 5
sdspfarm transcode sessions 8
sdspfarm unregister force
sdspfarm tag 3 mtp123412341234
02-25-2012 03:33 PM
It´s not possible to set any codec or to set maximum sessions higher than 0.
But the UC540 has resources.
Here are the specifications:
under table 9.
Do you have an idea why it´s behaving this way?

Hi Stefan,
This is actually quite normal
OK so a couple of things you need to do (Using CCA).
Once the reboot has finalised, proceed to do the following:
OK once this second reboot is finalized, you can load up CCA again and then change the FXS configuration if you want it to go into "User" mode, this will take up licenses and also will use DSP resources (STCAPP).
As bad as it sounds, sometimes the unit may require multiple reboots to get the configuration set properly and working, whilst it is not always the case and in theory you should never have to do it, the above procedure is what has worked for me many times in the past.
Cheers,
David.

But it´s still notworking. At the moment I have only one analog phone and an IP-Phone connected.
When I press the flash button on the analog phone the MOH can be heard on the IP-Phone.
When I press Hold on the IP-Phone, I only hear a short double beep on the analog phone.
What else do I have to do?

Hi Stefan,
Hmmmm I am wondering if this is a Multicast issue and related to the analogue ports.... I don't know to be honest and have not see this before so I am not a little miffed as to what could be causing it.
If you have a support contract on the device, it would be at this point that I would encourage you to open a case and get support involved, just to be sure that this is not a bug or something more sinister going on.
Cheers,
David.
