Re: cme 4.x + isdn problem

Hi,

under DP 2, you need "direct-inward-dial".

Hope this helps,please rate post if it does!

Re: cme 4.x + isdn problem

nope it didn`t help, can make call but no voice in handset at all :(

Hall of Fame Super Gold

Re: cme 4.x + isdn problem

May be AA on CUE is not set correctly. Try changing translation rule so that call is sent to a phone and you should be able to talk.

Re: cme 4.x + isdn problem

Most common cause of one way voice is a routing issue. This could be the phone or the router does not have a return router between each other, or the source address of one device is not reachable from the other.

We need to know if the phones are on the same local network as the CME system , or are they on remote IP subnets.

Otherwise paste your FULL config so we can check how the rest of the router has been set up.

Re: cme 4.x + isdn problem

My 2801 router is gateway to pstn (through isdn). Dialling is OK. I mean if I dial my mobile number it rings but when I pick up no sound in it. All ip phones are connected to this router, and AA is aim-cue it is working fine for ip phones.

Can you take a "debug isdn q931" with "term mon" for when you call out and no voice is heard.

Re: cme 4.x + isdn problem

Hi, I see that is suspicious:

Jun 25 15:01:26.867: %DSMP-3-DSP_TIMEOUT: DSP timeout on DSP 0/1:1: event 0xDC, DSMP timed ou

Which exact IOS are you running ?

Please upgrade to 12.4(11)XJ4 and check again.

Re: cme 4.x + isdn problem

I did upgrade to version: c2801-ipvoicek9-mz.124-11.XJ4 but still the same problem exists :( any help please

Hall of Fame Super Gold

Re: cme 4.x + isdn problem

Do you still see the same message in log ?

If so it can be an HW problem and you should try a different PVDM2 module.

New Member

Re: cme 4.x + isdn problem

yes still the same message ;(

New Member

Re: cme 4.x + isdn problem

i doubt i could be HW problem because when i force phones to use different codecs: one using g711ulaw and second using g729r8 voice is OK. So i think that router in this case is using dsp in proper way. Maybe i should configure dsp farm on my router, but i don`t know how. Please help.

Hall of Fame Super Gold

Re: cme 4.x + isdn problem

Hi, when you configure phones with different codecs, router doesn't enter the media path unless you also configure "dspfarm-assist" and transcoding.

You could also try removing the PVDM2 and would observe that the phones are still able to talk to each other even when configured with different codecs.

Perhaps you can take some DSP specific debugs to see if other error messages are thrown.

New Member

Re: cme 4.x + isdn problem

for example what debug would you like to see in order to help me???

Hall of Fame Super Gold

Re: cme 4.x + isdn problem

Sorry, I can't really tell what would be the "right" one because such a problem never occurred to me. Form the error message above I can tell that something is wrong with the DSP HW, but nothing more specific.

New Member

Re: cme 4.x + isdn problem

i need to be sure that it is the hardware problem i don`t have different dsp module to use. Can write me how to force phones to use different codec with dsp assist.

Hall of Fame Super Gold

Re: cme 4.x + isdn problem

You need to configure transcoding as per the administrator guide.

I think that is an overkill just to test an PVDM2 module that should be replaced by simple request from the vendor you bought it from.
