How many voip calls???

[SMART]

Hi
we need know how many voip calls simultaneusly support the rockets

protocol sip
and codec g729

Under good conditions and with IP packing or aggregation, 400+

Ron;
what is it with the legacy 802.11a ?

thanks ron but wath is ip paking?

We have a client with to much voip calls we need know if with rockets can i give the profecional service

in the base station we have a rocket and with the client we think put another

you have this test in raly live? 400 voip calls simult****ly???

Regards.

thanks ron but wath is ip paking?


You can't send each UDP packet as its own wireless packet. The PPS is just too high. You need to combine many small packets into one large packet to achieve high efficiency.

802.11a in general or UBNT 802.11a products?

[doush]

802.11a APs running mikrotik 433AH and Nano5 CPEs ?

[osnet]

Man, I run voip over my network and that generate a lot of PPS. I don't really think that the the actual firmware of the Rocket M5 can handle 400 voice concurrent calls with all those pps.

It's and issue of the Bandwidth it's more a packet per second that generate each call.

That's exactly why I wrote "The PPS is just too high. You need to combine many small packets into one large packet to achieve high efficiency. "

50 in a PtP setup, less in PtMP.

[SMART]

50 in a ptp setup, less in ptmp.

we are very confused

how many voip calls realy can make simultaneusly with 2 rockets?????????????????????

Please some realy know???

How can you do IP packing? is it only on Mikrotik Routerboard?

I already told you. If you don't believe me, try it out for yourself.

[Ron]

I think UBNT's M line does packet aggregation, but I haven't tested it enough to know for sure.

Besides, a RB750 is only $40.

[SMART]

Not with mikrotik¡¡

how many voip calls can pass betwen 2 rockets??????
In sip
and g729 code

mike

any answer????

[kijoma]

hi,

i like it when people are so nice to those people who try to answer their question..

The M products have packet aggregation, multiple streams are very efficient with this..

if you take a moment to browse the forum here or the relevant product data sheets you will see mention of packet aggregation, very important with a lot of small packets.. the overall effect on latency is negligible..

the best thing is get a pair of nano5m's and test em out.. they cant be any worse than what you have.. (oh and upgrade them to latest beta firmware first etc..).

cheers

thanks kijoma

but this forum is for thath, the questions to experts

how know how many voip calls support the rockets¡¡¡¡¡¡¡¡¡¡¡¡¡¡

[sldnkarm]

All,
once we get our RocketM5's installed and established in our 11mile test link I will be able to run Vivanet Assesor across it and provide some real VOIP test results for everyone interested.

Stay tuned...

we have over 300 sip phones on our system working perfect. all PtMP.... Rocket AP's using WDS.

thanks dayas..

This is very important for us
you can put some screen of this???
Is 300 voip calls simultaneusly??
Wath protocol??
Wath code??

Please we need this information for a large deploy

regards.... Smart

Look, anything over 24 SIP simultaneous calls using any Codec ( G.711, G.729 G.728, G.723 ) should be consider a professional and serious job.

The total of 300 simultaneous/concurrent calls using G.729 Codec or any other codec, ( not to downsize ubiquiti equipment ) will be impossible, not because the bandwidth but because the processor does not have the power to process 15K PPS *=( That's 15,000 packets per second ). The theoretical bandwidth needed is about 25 Megabits that could be done on a very good connection doing some kind of file transfer but not near close when you have 20 - 30 bytes packets that need an answer of about 20 ms.

I would guess less than 20 simultaneous / concurrent calls on a set of Rocket M5 with out using any other software or hardware. That's about 1000 PPS.
The total of 50 Calls could be done, But I will assume you will get a large amout of packets lost.

How many calls do you need?

Hope this helps.

we have over 300 sip phones on our system working perfect. all PtMP.... Rocket AP's using WDS.In use simultaneously or just accounted for?

[treichhart]

I am wondering the same question about voip using ubiquiti products.

[dayas]

In use simultaneously or just accounted for?

300 total not simutaneously. G711

[SMART]

300 total not simutaneously. G711


buuuuuuu
we need how many voip cals,,,, concurrent, simultaneus, at the same time

[SMART]

mike¡¡¡¡¡¡¡¡¡¡¡

the ubnt team know some??????????????????????????

[WHT]

From the CPE loading point of view for a Rocket, figure on 90 to 100 connected users.

From the CODEC point of view, roughly one users per one Kbps of data throughput... ROUGHLY. In other words, you might push more or less, but certainly not ten or twenty times as more.

There are many, many variables..and you want a fixed number, NOW. The best you'll get is an estimated min and max...but certainly not a guaranteed number.


Added...For some reason, this all smells like a marketing driven idea, with very little wireless technology people involved.

[Aveyer]

My guess is around 150 concurrent calls max.

[dayas]

i would think you could achieve move than 150 concurrent calls. Either way if you are offering services that require more than 150 concurrent calls that is a good problem to have.

[Ron]

When dealing with someone named "SMART," you should know to expect the exact opposite.

[ridnet]

OK MAN, this this the final answer.

100 Mbps / 87 Kbps = 1,149 cuncurent calls.

If it does not work, e-Mail the ITF , let them know the Codecs have bugs and you have to request an update from the ITU, ask for an ETA on the final upgrade, it has been 38 years with out one.

Never, ever think it's a problem with the radio or any of the components inside.
