I have looked up the topics with the same problem that do have I but found no solution to it. The problem is with IP telephone. We have two MT 2.8.24 routers connected together. The scheme is the following: internet => MT1 => MT2 => clients home router => IP phone
When the client is calling somebody, he listenes perfectly but the person to whom he is calling listenes very badly with lots of interruptions.
I thought that the problem was that on the MT1 there were no rules for the phone but i have made them. the problem didnt disappear. the rules are as follows:
MT1:
[admin@MT1] ip firewall mangle>
0 in-interface=ether1 dst-address=1.2.3.4/32 action=accept mark-flow=phone-up mark-connection=phone
1 in-interface=ether2 connection=phone action=accept mark-flow=phone-down[admin@MT1] queue tree>
0 name=“phone-up” parent=adsl flow=phone-up limit-at=128000 queue=ethernet-default priority=5 max-limit=196000
burst-limit=0 burst-threshold=0 burst-time=0
1 name=“phone-down” parent=ether1 flow=phone-down limit-at=128000 queue=ethernet-default priority=5 max-limit=196000
burst-limit=0 burst-threshold=0 burst-time=0
MT2:
[admin@MT2] ip firewall mangle> pr
0 in-interface=int1 dst-address=1.2.3.4/32 action=accept mark-flow=phone-up mark-connection=phone
1 in-interface=int2 connection=phone action=accept mark-flow=phone-down[admin@MT2] queue tree>
0 name=“ip-phone-up” parent=ALL-Up flow=phone-up limit-at=128000 queue=ethernet-default priority=5 max-limit=196000
burst-limit=0 burst-threshold=0 burst-time=0
1 name=“ip-phone-down” parent=ALL-Down flow=phone-down limit-at=128000 queue=ethernet-default priority=5
max-limit=196000 burst-limit=0 burst-threshold=0 burst-time=0
when I tested the phone in my office the speed was 64000/64000 and it was enough with the priority 8.
any brilliant ideas?
