I have a lot of delay in a BRI link to a PRI. I applied QoS CQ,PQ and doesn't worked, and I have a 1600 with 11.3(11a)in a branch and a 3640 w/11.2(11)P1 in a central site. The voice quality is fine before to begin data traffic.

Hello,
have you tried Class-Based WFQ ? I assume you have ppp multilink enabled for the BRI ? Can you post your config ?

I'm not sure but I thing that this configuration, don't have PPP multilink.

Hello,
ppp multilink is not active. You can configure it by adding the command ppp multilink in interface config mode to your bri interface. Also, set the dialer load threshold to something like 127 (which equals 50% load). If this doesn't help let me know and we can configure a voice prioritization scheme.
Regards,
GP

Thank you, Georg,
I tested configuring ppp multilink and the problem continued. Can you try to configure some scenario with voice prioritization traffic, because VoIP is running over a DDR link but with a third party equipment (external IP solution).
