Question on MGCP IOS transcoder and Software CFB
I am using my BR1 router as a MGCP GW. I have configured IOS based
transcoder on this MGCP GW and successfully registered to CUCM. I am using software
based conference bridge on the CUCM which is in a different
Devicepool/Region. Between Regions G729 codec is negotiated. In this
case when I try conferencing 2 BR1 phones with a PSTN call, the BR1 Phone initiated the conference is hearing a busy tone and other BR1 phone gets connected solely to the PSTN.
Once I moved the software based conference bridge on the CUCM to BR1 device pool everything is working fine.
tried to replicate the same with H323 GW and I do not find the above
mentioned issue. I am suspecting if we can use IOS based transcoder on
MGCP GW and Software based Conference bridge on CUCM which are different
Please let me know if my understanding is wrong. Please find below my configuration.
