Hi Miron Very strange … Fot this lab, I had an issue with rsvp as well, but not the same pb. In the dspfarm configured as mtp, I put the codec pass-through command line to have an ILBC negotiation. Without this command, g729 codec negotiation instead. But your negotiation iLBC seems to work Alerting 47.2 kbps, round up to 48k Connected should be 31.2 kbps for 1 call you have 31k…. fine Same results with debug ip rsvp signaling ??

Hello,
I'm working on vol2 lab8. QoS task requiresRSVP locations based CAC between HQ and BR1. I configured it as usually, but I get strange results when I make a single call between the 2 sites: Before the call: RS30-CCIE#sh ip rsvp installed RSVP: Serial0/0/0 has no installed reservations RSVP: Serial0/0/0.30 has no installed reservations In alerting phase: RS30-CCIE#sh ip rsvp installed RSVP: Serial0/0/0.30 BPS To From Protoc DPort Sport Weight Conversation 76K 10.225.101.254 10.30.101.254 UDP 17270 16410 6 266 48K 10.225.101.254 10.30.101.254 UDP 18160 16524 9 265 When connected: RS30-CCIE#sh ip rsvp installed RSVP: Serial0/0/0.30 BPS To From Protoc DPort Sport Weight Conversation 76K 10.225.101.254 10.30.101.254 UDP 17270 16410 6 266 31K 10.225.101.254 10.30.101.254 UDP 18160 16524 14 265 After disconnecting the call: RS30-CCIE#sh ip rsvp installed RSVP: Serial0/0/0 has no installed reservations RSVP: Serial0/0/0.30 has no installed reservations I can't explain, why CUCM makes 2 reservation for single iLBC call. AFAIK, it should be 48K in alerting and 31K in connected states. But why do I get this 76K? I configured everything as usually: RSVP reservations are optional, traffic should be remarked to CS1 when no bandwidth is available. RSVP agents are invoked correctly... Any ideas? regards kobel -- This email was Anti Virus checked.
