[cisco-voip] Convert Progress to Disconnect ISDN Q931 Message

[Tim Smith]

Have you checked the interoperability portal yet?
http://www.cisco.com/en/US/solutions/ns340/ns414/ns728/networking_solutions_products_genericcontent0900aecd805b561d.html

You didnt mention anything about versions or even the Siemens platform.

These docs contain a good guideline to what features actually work, and if
anything needs to be tweaked, or if there are any limitations.

They include the key config for both sides as well.

Cheers,

Tim
