audio problem after upgrade to 3cx Phonesystem 11.

[mic.max]

After i've upgrade from 3cx 10 to 3cx 11 phonesystem, when i receive call in most case (50% of call) the audio voice in output is very bad and incomprensible. With 3cx phonesystem 10 no problem.

My configuration is:
3cx phonesystem 11.0 on server Windows 2008 R2 Standard (x64) configured with IIS 7.5
Gateway Grandstream GXW-4104 (fw 1.3.4.13)
n. 3 Phone SNOM-870 (fw 8.7.3.7)

Thanks for your reply

i think i've solved a problem. I've activated on network IPv6 protocol and the problem seems not to occur. i test for next day...

Hi Mic,

What did you activated on IPv6? I Just want to know the solution you came up regarding this issue because i might encounter this if i will upgrade my v10 to v11. Hope to hear your response.


Thanks,
