Have a CUBE on 3800 with 15.14M(6) with SIP to SIP dial peers. Some external inbound callers at times can hear no audio streaming from IVR.
I run a traffic capture from the LAN side of the CUBE and I can hear the audio.
I run a traffic capture on the WAN side (towards caller) and i hear nothing, BUT the rtp stream is active (50 pps G711a). When i replay this stream on Wireshark i hear silence exactly what the caller can hear...
G711a on both sides but no audio is heard on the WAN side exiting the CUBE towards telco
DIal peers matched= 31 In from itsp and 40 Out to CUCM
Setup:
ITSP--SIP Trunk-- MyCUBE--SIP Trunk--CUCM--IVR(CTI Ports and RPs)

personally I would make the following changes to each dial peer sticking to one dtmf relay form and add the following changes:
dial-peer voice 30 voip
description Outgoing call leg from CUBE to ITSP
translation-profile outgoing StripZero
destination-pattern 0T
session protocol sipv2
session target sip-server
session transport udp

HI,
itsp requires inband dtmf only and G711a
01-30-2014 02:27 AM
I can see that you are applying your sip bind statement on loopback5..
sip
bind control source-interface Loopback5
bind media source-interface Loopback5
The question is this.Can your ITSP connect to that interface?

hi,
Yes my itsp can connect and see that interface. Most calls work and only some fail. Intermittent. I have incuded a "show call active voice" for a "failed" incoming call from 0204002244 to 0498870440 . What happens here is silence to external caller coming in on dial peer 31 but there is an RTP stream being sent to him. Wireshark trace on WAN side proves silence within RTP stream exiting CUBE towards callers SBC at 10.193.202.100 from my cube at 10.66.41.1

My suggestion will be to upgrade the IOS on the CUBE. Since this is intermittent..However I suggest that you enable debug ccsip messages and confrim that for those calls that you are getting silence on, the call path is the same. Ie ensure the the media parameters are the same...If it is the same, then upgrade IOS.
