SCN Fails after upgrading to v5 4

[hairlessupportmonkey]

Odd one here.

2 x 406v2
both were on 4.2(xx) prior to upgrade and ASCN was working great, apart from an unfixed bug - so a v5 upgrade was to resolve it.

scenario

UK <---SCN via VPN --> US

VCMs all OK and working.
Licences are OK
Removed obsolete Licences

Sysmon shows SCN is up and running.
Shows all users and information and BLF.

SSA on the UK side responds that the SCN is down, but sysmon shows it up.

when you try to call over it, you see the call in the monitor trace attempt on both sides, fails and gives unobtainable.

have escalated to Avaya, but any input would be great.

P.S - on V5.0(15)

cant take it to .18 until after hours.

I had the same issue and I am using short codes for extension dialling between sites like 3xxx, dial, . , XX.
While this is not a resolution, it bought me some time on a busy SCN.
Then I addded IP Routes (I previously just had a catch-all of 0.0.0.0, 0.0.0.0, 172.172.172.1) and deleted the short codes and the magic started happenning.

Something to try anyway.

Mike,

cheers for that.

I tried forcing 7XXX over the SCN with no effect.

I added specific routes and blanket routes.

also no effect.

HSM what are you running for firewalls on this? Something has changed between 4.x and 5.0 in the SCN traffic and i have had like 10 sites do this and it was always something on the firewall.

Sonic walls.

Im also thinking something with the networking side is causing this to fail too.

 

[kwing112000]

it is the H323 stuff on the sonic wall. i have had the exact issue. I think it is called H323 transformations..

OK - lemme check with he user.

 

[hairlessupportmonkey]

OK Good call - we turned off the H323 Transformations rebooted the US switch and its all working.

I love you - thanks!

Stars for you!

kwing - I have been going crazy for hours trying to figure out what my problme was. The SSA said said SCN was up but calls would not make it through. I checked my sonicwall tz170 and sure enough the H323 Transformations were enabled. Turned them off and BAM call are making it through. Thanks Alot!

Does anyone know if there is anything like this in R6 - I am supposed to upgrade this week.

[hairlessupportmonkey]

Id be safe to assume that the fix we just applied will also be OK for r6

I made an FAQ

Get well soon Aaron.

 

[hairlessupportmonkey]

hahaha - cheers Tom

 

[TomMills]

I think we do need to start putting more stuff like this down in FAQs it makes it easier to find, and sooner or later most of us will need this information.

Im just trying to be more helpful.

I have had this happen on a few different firewalls with R5. on Juniper it is the H323 under ALG and with Cisco it is the fixups/Inspect options.

[hairlessupportmonkey]
