Hi, Are you sure that this is an Asterisk problem? Configure an IP phone, ATA, or softphone to connect directly with the provider, and check the quality. If it's bad, use tools such as http://www.testyourvoip.com/ and http://www.pingplotter.com/ to troubleshoot.
If standalone phone works ok, compare with *. Same codec? Same packetization? If not, adjust * to match. If they're the same, please provide info on your Internet connection upload speed, codec, type of client phones, etc. --Stewart > We are using [EMAIL PROTECTED] 1.5 and SIP trunks to communicate to the PSTN > network.
