Hello,
We got a IP500 with software level 5.0(8) with a sip-trunk.
On the IP500 we connected 10 x IP1608 phones, 2 x IP1616 and IP Dect R4.
The switch is the HP 5604xl.
We got 2 vlan's. A data vlan and a voice vlan. We set the qos on for voice.
The IP500 and the dect is on a untagged port and the phones on a tagged port.
The codec we use is G711 a-law.
Now if we call outside with the sip-trunk, we got a noise on the phone.
We tried difference things, like direct media path off, other codecs, other switch with default settings, 100mb full duplex for the IP500 and the phones, etc
But nothings works. We got still the noise.
Have anyone a suggestion what this is?
