PRI One way voice issue

[h0lle]

Hey guys!
I have a V2 8.1 running pranks on me.
If this would have been sip it would have made more sense but I'm running 4xPRI.
Two times now, we've had one way voice in MDA/MEX-cellphones (or what you call it overseas). The one calling to the pbx can hear but not the one answering in his cell. Same if customer-cell call external. Last time this occurred to 4 users that I know about, of over 300 users. Tried calling several others without problems. Reboot and back on track! Lost my monitor-traces but doesn't even have a clue what we're looking for anyway?

Do any of you have any experience in similar problems? Would like to be more prepared if and next time it happens so I can do some quick tests before trying to find a slot for a reboot.(And later hardware or software-replacement of course). One thing I know I forgot to try was to test if DTMF passes through.

Thanks for your time!

Clocking source is set to carrier? If network is unsuitable, is it set to the first PRI trunk?

In monitor under ISDN events or errors you may see "Falc Slip Store 0"

Direct Media Path on IP handsets?

All four are set to network, should I try having just one? All ip-extensions have allow direct media path. No falc slip so far in monitor.

 

[holdmusic34]

I believe the first trunk only should be set to network. i.e. only 1 trunk per system set to network.

You lose, Carl Miller.

You should only setup one line to use network as clock source. Othe lines can be configured as fallback.

Try upgrading to 9.0 FP5

IPOFFICE-78245 Twinned call to external number (using FNE32) with no talk path

There are some other fixed on Twinned Calls as well, had a lot of issues with one-way speech on a SE with gateways before upgrading.

Thank you very much for your answers. I've set only one pri to network and will push to get the upgrade done!

what is the process to upload license in ip 500 v2 through manager

 

[h0lle]

astralastral; You should make and own thread, but this is how it looks:
License to the left, ctrl+n , ctrl+v of the license key. Merge.

 

[amriddle01]

You can actually just click on the "Licence" column then do Ctrl V/Paste and the licence goes straight in, there is no need to select "New"/Ctrl N first

And if adding multiple licenses you can paste all of them at one time.....
