Calls with bits of silence

[jgraham1075]

IP Office 412 with 4.0(7) AND 4620 IP Phones

Anyone have any issues with calls that contains sporadic 1-second bits of silence?

We are using G.711 ULAW 64K and do not have VoIP silence suppression checked. Gain is default and H450 support is None.

We have incoming PRI T-1 lines for all calls

It seems to happen on both external and internal calls

Any idea what I might adjust to resolve this issue???

Thanks

just curious, but why do you have H450 support off? i always heard that you should always have it set to H450.

I have a few 4.0.7 systems out there with IP sets and we are having nothing but issues. I have heard there are some private builds that have new phone firmware that is really helping. I will be putting one in on Wednesday i will let you know how it goes and if it helps.

I also have a few 4.07 ip phone set systems and always always getting problems, rebooting, crashing, screens going blank.

of course it gets blamed on customer network, but hell, every network has issues, how sensitive is the equipment???

I have installed many ip phone systems on networks that shouldn't have worked and no problems.

this is where avaya lag behind, the phones need to be able to ignore all traffic except h323.

I never ever had any problems with ipphones
I have installed more ip then digital or analog

Do everybody upgrade the phones ???

IP Phone speech problems = network issues

Pretty much 99% of the time.

QOS, VLAN !

Its not the IP Phones fault that the network is not capable of carrying the voip packets back and forth in time, hence bits of speech missing.

If the network is up to it the IP phones certainly are.

9 times out of 10 you can whack IP phones on and they will work, you will however find networks that need a tweak to get them working.

It is merely down to the way that voip needs to work and they way that the existing network is working.
