Hi,
Ser has a few cmd which allows rewrite request uri or some part of it. Does
SER have some cmd which allow rewrite caller uri or some part of it?
For example, my uri is 1767(a)mydomain.com but when I'm calling outside of my
VoIP world to PSTN (for example through Cisco call manager) I would like to
identify myself by E.164 address format, i.e. +4214151341767(a)mydomain.com.
It should be helpful for me change my URI.
Thanks,
palo
