Hi, we have some problems with outgoing calls from 7912 connected to 4510r switch, calls from 7940 is ok, but then we call from 7912 after some time voice is become very bad and city abonent can't hear us or we can't hear abonent. ( we have to 4510 switches with same ios and configuration on one 7912 work normal on second it work bad ). Does anybody hear about such kind of problems ?

Voice quality problem is mostly related to network problem. Asymmetric routing design is also part of the cause. Connect two sniffers to 7912 phones and make some test calls. When you get a bad call then please send the sniffer trace.
