Please try explaining with more words, having to do an interrogation by email is so annoying and slow.
Even if your english skills are less than perfect, try :-) (I guess most of the RIPE participants don't have english as a native language anyway)

So, from above I guess:

you are AS50223 Alfa Telecom CJSC located in Kyrgyzstan peering with AS8449 Join Venture Company "ElCat" and AS12997 JSC Kyrgyztelecom

According to bgp.he.net you announce these prefixes:
46.251.192.0/19	Alfa Telecom CJSC
46.251.200.0/22	Alfa Telecom CJSC
109.71.224.0/21	Alfa Telecom CJSC
109.71.224.0/22	Alfa Telecom CJSC
109.71.228.0/22  Alfa Telecom CJSC

According to RIPE RIS you have these:
Prefix  Size  Last seen  First seen  Whois Registry Peers seeing
46.251.200.0/22	22	2012-02-15 08:00:00 UTC	2011-10-19 07:58:53 UTC	W	RIPE NCC	95
109.71.228.0/23	23	2012-02-15 08:00:00 UTC	2011-04-30 16:55:04 UTC	W	RIPE NCC	2
109.71.228.0/22	22	2012-02-15 08:00:00 UTC	2012-01-19 08:43:07 UTC	W	RIPE NCC	101
109.71.224.0/22	22	2012-02-15 08:00:00 UTC	2011-10-14 21:34:10 UTC	W	RIPE NCC	95
109.71.224.0/21	21	2012-02-15 08:00:00 UTC	2011-10-14 21:34:08 UTC	W	RIPE NCC	103
109.71.230.0/23	23	2012-02-15 08:00:00 UTC	2011-10-14 21:31:32 UTC	W	RIPE NCC	2
46.251.192.0/19	19	2012-02-15 08:00:00 UTC	2011-10-14 21:34:08 UTC	W	RIPE NCC	103


The route you mention
route:          2.16.56.0/23
descr:          Akamai Technologies
origin:         AS20940
and is part of  2.16.0.0/13

BTW I see these on some of my routers as:
2.16.56.0/23       *[BGP/170] 2d 09:41:05, MED 3593, localpref 110
                      AS path: 3549 20940 20940 I
                    > to 64.211.195.225 via xe-5/0/0.0
                    [BGP/170] 4w0d 23:14:11, localpref 100
                      AS path: 16245 3292 20940 I
                    > to 83.221.128.125 via xe-2/0/0.0

2.16.56.0/23       *[BGP/170] 2d 09:41:14, MED 3593, localpref 110
                      AS path: 3549 20940 20940 I
                    > to 109.238.48.254 via ae0.94
                    [BGP/170] 1w6d 08:06:05, MED 0, localpref 110
                      AS path: 3356 3549 20940 20940 I

So it would seem you have received these Akamai prefixes correctly, a good start

Then hopefully we can get down to your problem.

"I have to you have a question? If an ISP blocks the transit traffic is what rules they break, and if we can resolve this issue through Ripe?"
 
and
"
Our two path. (Our AS50223) Example:
*> 2.16.56.0/23     212.42.96.            0    260      0 8449 3216 2914 4436 20940 20940 i
*                   213.145.131.           0    255      0 12997 9198 20485 3549 20940 20940 i
by 8449 it works, but through the 12997 does not work.
12997 says that 9198 blocks. On many forums, users are complaining that the 9198 block sites.
On the request is silent and does not meet.
"

Do you have a problem reaching Akamai - do you have problems reaching other destinations?
Do other have problems reaching you?

Do you have problems with all your own prefixes/addresses?

Can you use some traffic - like doing ping? but not UDP? or TCP?

Include more information such as destination addresses tried, and traceroutes to known destinations that should work.
- I would do the test from each of your own prefixes

More information is need to help you :-)



BTW I found most of this on:
http://bgp.he.net/AS50223
http://bgp.he.net/AS9198


Let us know if there is something wrong in the things we guess, so we can get to the matter of the problem :-)


Best regards
