Thanks Olle. I've tried tos=lowdelay and tos=throughput, and both "do" set the appropriate tos bits in the IP header. For those that might be digging through the archives, one can set the tos bits via two different mechanisms: first, as shown in the iax.conf samples, sip tos bits can be set towards the top of the sip.conf file using: tos=lowdelay ; or tos=throughput, etc. or, tos=0x18 ; where the tos bits are set individually and in combination For example tos=0x10 = low delay tos=0x08 = high throughput tos=0x04 = high reliability tos=0x02 = ECT bit set tos=0x01 = CE bit set or one can set multiple bits, such as tos=0x18 to set both low delay and high throughput. For those that might be sending sip/iax packets across the Internet, many of the backbone ISPs now honor the QoS/TOS bit settings.
