Hello All,
We are pushing IP phones out to our branch offices.
We have a 3662 that connects to the PSTN via a PRI.
All of Remote office voice traffic routes out to the PSTN via the 3662 PRI connection.
We are using a 3640 as our DSL shelf plugged with G.shdsl cards. The 3640 uplinks to our 3662 via a FE port.

Each remote office has a 2621 and a 3524 switch.

Everything routes.In the testing phase everything worked flawlessly. Voice/Video and Data all route correctly. We installed more phones at the remote sites and ran into Voice Quality issues.
I am a newbie to the G.SHDSL card. Has anyone deployed this with LLQ and QOS via a policy map.
Does the QOS go on the ATM or Dialer?
Is it similar to Serial and Multilink interfaces?
If anyone has hands on experence please give us some assistance.
Thanks,
Billy
