Hi, I followed the onsip.org <http://onsip.org> guidelines for using ser +mediaproxy. I attached asterisk as a voicemail system. When a call from the PSTN is placed to an IP user that is behind NAT, the audio stream goes through the mediaproxy without any issues. When the same call get forwarded to vm (asterisk) the call fail with a 488 from asterisk, as well as with errors such as: use_table(): invalid parameter value is_local() error while trying to use domain ser, mediaproxy as well as asterisk are on a public address. Has anybody had asterisk running as a voicemail with the onip config? Thanks. Samy.
