what are the symptoms?

If you use only G711ulaw same issue?

For internal conferences same issue?

when u noticed this behaviour?

CCC is EoS almost end of support we are encouraging our customers to go to MPE

You can check: CSCee92393

Audio quality issues when using multiple RTP packet sizes

Configure all devices to use the same packet size, such as G.711ulaw 20ms.

This is not possible in all cases

As long as i do conferencing within uae, no audio degrade happen. when users from other pstn or celllular networks connects lets say 4rom germany, turkey. the audio quality degrades,, i.e. scattered audio, echo, delay.

we have e1/pri. also in cucm 413 we have settings on gateway(mgcp) PCM type:alaw while on gateway : it is ulaw under dial-peer

when any call connects its shows in show voice call summ "g711ulaw" as codec..

Is it happening coz of mismatch on cucm & gw the pcm type
