of course, another quick check is to hit the i button (or ? button on the phones) and see if the Rx/Tx counts are incrementing. thanks, /Baktha On Thu, Feb 9, 2012 at 12:41 PM, Baktha Muralidharan muralic...@gmail.comwrote: could you attatch outputs of show voip rtp connections show sccp connn show call active voice brief thanks, /Baktha ___ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com Are you a CCNP or CCIE and looking for a job?

Re: [OSL | CCIE_Voice] No Audio on TEHO calls from H.323 to MGCP Gateways
I think the reason is a codec mismatch between the transcoder and mtp. The MTP probably has g729r8 support but the transcoder lacks this codec in the list. Either add g729r8 in the transcoder on both routers or add g729ar8 within the MTP on both routers. Vik Malhi – CCIE #13890 Managing Partner - IPexpert, Inc.
