One way audio after a few minutes after upgrade.

[Bas1234]

Hello all,

We have 5 IP500's in a SCN all had 4.2.4 without any problems. After upgrading to 5.0.8 One way audio after a few minutes occurred. Downgrading back to 4.2.4 resolved it. Now they have put the error on caveats;

CQ89037 | One way talk path occurs in the middle of a conversation across the SCN | 5.0.8 | SP_RELEASE_1Q10_5.0 | 3-Available

Did an upgrade to 5.0.15 and the error came back. We used G.711 as a system wide codec, DMP ticked on the user but untick (also tried to turn DMP on)on the SCN links. The setup was still in a "Star" network.

Any of you who have the same problem?

PS.

It's Internal, external and over SCN. The network is a 1 Gig fibre network, only one of the 5 has a VPN connection.

odd we had the opposite recently. v4.2 switch decided to only offer one way speech.

upgraded to 5 sorted it!

we have around 8 switches in star mpls.

perhaps there is a bug in the vcm firmware in v5?

We have 2 customers with more then 4 IP500 running 5.0.15. (new install). And 2 customers like above the one who where "upgraded" to 5.0.15 And they have the one way audio problem.

I think the upgrade causes this but i'm not sure, and i'm not (yet) going to re-program those IP500's.

Let see how it goes today, upgraded 1 site (4 IP500) to 4.2.23.

Try the mesh network and see what happens.
It must be related to something else.
If an upgrade does do this you could try a factory default and shoot back a config (use the reset button)

Try the default method that tlpeter suggests and also, delete and recreate the IP lines. I'm pretty sure I've seen corruption caused by v4 to v5 upgrades on IP lines (you'll notice that the configuration form in Manager looks different).
