Having a problem here that I can't seem to find a fix for. PSTN call comes in, operator answers, transfers call to a phone behind an IAXy. Caller hears no sound after being transferred. IAXy can hear caller, but not vice versa. Client reads: NOTICE[11342]: channel.c:1950 ast_read: Dropping incompatible voice frame on IAX2/jim-7 of format gsm since our native format has changed to ulaw Not sure how to proceed. Please advise. Thanks, Jay
