We have a network that contains Cisco 7941 Cisco IP Phones that have been working fine.
We are now begining to experience problems with phones getting IP addresses from the data vlan rather than the voice vlan?
We had a Call Manger upgrade in December but no other changes since the problem is intermitent but constant.
There was a similar post a whil ago where the solution was to change the swith port mode from access to trunk.
Don't understand why this would have worked and the post did not fully explian.
Any suggestions, help would be really appreciated as this issue is ongoing with no end in site.
If the original contributors have further information re their solution would be gratefull for their input.
