I have an ASA5505 running 8.21 but I am having trouble setting the option 156 on the ASA for the Shoretel phones. I have done this in the past on Cisco routers and numerous other types of devices. I was assuming the ASA would be similiar but it appears to be different. In the past I have used dhcpd option 156 ascii "ftpservers=192.168.2.1 layer2tagging=1 vlanid=2", but when I try this one the ASA (both in the CLI and the ASDM v6.21) I get an error - Too many ASCII strings from the CLI, and ASCII Data cannot contain spaces from the ASDM - which is why you use the quotes (at least in the Cisco routers). I have searched the forums and I have seen other people with this same issue and everyone directs them to some old link about a Cisco router assuming they are the same...they aren't  Let me know if anyone has any ideas...and thank you for your help.

Ahhh, something I didn't try...comma's in the empty spaces...I will try it right away...didn't know that would potentially work...I will let you know, thanks again.

That was it, worked like a charm...I knew it was something simple, but I could not figure it out...and Cisco's documentation wasn't helping either...thanks again.

This is why I come to this site first rather than searching through pages and pages in a manual. Simple answer that just fit the solution and easy to understand for anyone learning, such as myself. Oddly enough its these answers that stick with you when you are doing other things. "Yeah, use a comma instead of the space". THIS SITE IS GREAT!!!
