Hope you are doing well. :)
i have a small concern about voice and data, can i create a vlan for both at the same time, i mean for example, can i use the same vlan for data and voice traffic??
also one small thing, what is the type of the port should i use when i connect an IP phone and pass a cable from the phone to the laptop, can i do this??are they gonna work both??
your feeds are highly appreciated.

A1) You can run IP Phones and data on same subnet - and without any QoS. I do that with 4800 Nortel IP Phones on 500 different locations. But you to follow some rules.
* I need to have have enough bandwidth and very low latency. I have 1 Gbit and less than 1 ms latency end-to-end
* You need to bee 100% sure that your PDS cabling can manage af category 5E test
* On my Nortel 1120/1140 IP Phones there is two ports - one goes to the swtich and the other goes to the PC.
Hope this short comment help you

thx a lot for the useful information.
about the rules or the stuff i have to take care of, i guess my switches are 100 not a gig, so only this gonna make me issues.
regarding the cabling , all of the cables used in my site is CAT6 so i guess this is fair enough.
so for now, and regarding the info i gave you, do you advice to use two different VLANs instead of one VLAN?
am i going to face any issues also if i use two different vlans??
thx again man, appreciated.

There are a lot of things you can do, but should not. The best practice is to have a separate vlan for voice traffic. Create a vlan, name it "voice", and issue the voice command inside that vlan interface. This will enable LLDP-MED (http://www.networkworld.com/news/tech/2004/110104t
