[Asterisk-Users] Suggestions for tunning SJphone with Asteris k?
Did you try using Sjphone with allow=alaw in sip.conf instead of g729? In our Asterisk Installations we used: ... allow=alaw allow=ulaw allow=gsm ... and didn't have any echo or scratchy problems. Hope it helps... Regards Guido Hecken> -----Urspr?ngliche Nachricht----- > Von: Chuck Bunn [mailto:chuck.bunn@networkdoc.com] > Gesendet: Donnerstag, 17.
