Hi, Does SER have any control or any can it be configured (if yes, please guide) to implement various QoS mechanisms like Diffserv,RSVP, Admission control etc.., to improve the voice quality and delays and/or jitter? Because lately, we are facing a decrease in call quality in our ser calls. Or do we have to do this only at the network level, eg. Routers etc..? Any poiners/guides will be most welcome.
