An administrator is troubleshooting why users are not hearing audio when dialing long distance
numbers across their Cisco Unified Border Element. The customer’s carrier has a requirement that
dialing long distance requires an access code to be entered. Looking at the exhibit, what two actions
can be taken to correct signaling? (Choose two.)
B and E seem right; Early Offer triggers media setup early, and Mid-Call Signaling fits access code changes.
C/D? Enabling the supplementary-service media-renegotiate (C) makes sense to handle changes in the call after initial signaling, which fits if the access code triggers a mid-call event. Media Flow Around (D) helps keep media direct between endpoints, reducing delays or drops that might cause no audio. B (Early Offer) is useful but if the carrier needs an access code mid-call, renegotiation could be more critical here. A and E don’t seem directly related to this issue.
I’m ruling out A since PRACK is more about reliable provisional responses, which doesn’t directly impact audio in this scenario. D makes sense because Media Flow Around helps media bypass the CUBE, reducing chances of media blocking. For the second action, C could be useful if the carrier requires re-negotiation of media mid-call, especially with long distance calls that might trigger supplementary services. Early Offer (B) is good for quicker media setup but only if the carrier supports it, which we don’t see confirmed here. So maybe D and C are safer bets for fixing no audio issues across lo
Maybe B and D—Early Offer for better media setup and Media Flow Around to keep media direct.
I’m thinking D might help because Media Flow Around can reduce media path issues causing no audio. Also, maybe C since supplementary-service media-renegotiate allows media changes during calls, which might solve the signaling problem with access codes.
Option A could cause issues if PRACK isn’t supported by the carrier, so probably not that. Option B sounds promising since Early Offer often fixes media negotiation problems with access codes. Also, E might help since Mid-Call Signaling Consumption deals with signaling adjustments mid-call.
