SkyStone / Skype / Voicemail Issue

Hi,


I have purchased the Skystone software for Skype and my UC520 which is great. I have an landline number attached to my skype account.


However when someone calls my Skype landline number  the call is routed to the correct phone (2001) however it doesn't drop into voicemail when I dont answer, Instead the user is requested to enter their extension ID...


However when I call the same phone (2001) from my softphone (2002) when I dont answer it drops into voicemail as it should...


What is the difference between a direct ext to ext call versus a skystone call being directed to the extension (2001)?


The message is "Enter your ID followed by #"....


Thanks


Brian

Hi Brian,


Can you please post the following debug for a failed call, meaning, let it go to voicemail all along.


debug ccsip messages


Along with the config, this will tell us what's going on.


Thanks,


Marcos

Hi Marcos,


Where does the debug information go? I enabled made a coupld of calls 1 that went to the cisco unity express main menu (which it shouldn't) and the other a successful call that dropped in to Vmail. I then stopped the debug.... However I dont know where the log is?


Can you help me?


Thanks

The debug needs to be captured on the UC500, not the CUE. SO, telnet to the UC500, login, type "enable" and then do "terminal monitor". Then, type "debug ccsip message" and make the call. Let it go to voicemail and send me all that output.


Thanks!

Hi Marcos,


I hope this makes sense to you...


I have attached the debug and the running config....


Many Thanks for you support......


P.s. Any news on the larger flash cards yet for the UC520?

I would love to see


"debug voice ccapi inout"


as well...


Make two calls.... one from the line that does not work and then hit a bunch of *********** astericks...


Than call from the softphone that works...

Marcos Hernandez Fri, 08/14/2009 - 07:05

Is this the full output? The debug seems incomplete...


I need to see the calling number/ redirect number in the initial INVITE.


Thanks,


Marcos

Could you describe the call flow of what is attached?  When I look at the logs, all I see is a call into voicemail without a redirect number, which would explain the behavior that you are seeing.



This means that I am only getting the final part of the traces, or that is what is happening.  How are you gathering the traces?

Hi Brian,


Can you please provide the information (call flow) that Steven requested?


Thanks,

Hi Marcos,


Appoligies for the delay. I have created two debugs CCSIP and CCAPI as well.


Hope these help.


The first call drops into the "Please enter your extension" then I do nothing and then it goes to "welcome to Cisco Unity Express...."


The second call drops into the voicemail correctly "2001 is busy please leave a message ...."


Thanks

Hi Brian,

Try this.


config t
voice service voip
no supplementary-service sip moved-temporarily


This should change the behavior of the transfer to voicemail.  Let me know how this works for you.

Hi Steven,


I tried what you requested, when I call from Skype or mobile in the system I now drop into the voicemail as expected however, when I hit the messages button on the cisco phone to check for vmail there is nothing there... You have no new messages even though I here the beep and press # when you finish...


You can try and call yourself Skype ID R37747 or Skype Landline +44 131 208 2486


Thanks

Any resolution yet?


Funny thing is your CCAPI IN/OUT debug shows the first call on dial-peer 20003 going to "called number=2001" and then I see the "called number=2099" on the 2nd call..  using dial-peer 9999

Hey John,


No resolution yet.....


Its weird since I added the addtional commands, when I dial either from my softphone or skype they both drop into the voicemail as they should... However calls from Skype or from landline to skype dont seem to leave a vmail even though it looks like they have dropped into it....


When I check by either dialling 2099 or pressing the messages button and leaving messages from both resources I only seem to have the vmail from the softphone....


Thanks

I tried calling in and received the VM greeting.  I pressed #, but I didn't get any responce.  The problem sounds like IP traffic might not be making it to the CUE module.  Can you get a sniffer from when you try to call and leave a VM from your computer?

Just disable the access-lists for now...  try that.. I bet you changed the default IP subnets and you have an old access-list in there blocking stuff up.

Hey John, Wont disabling my access list make my system vulnerable ?

Brian,


There are multiple access lists...  some protect the interface to the internet and other deny traffic from the data vlans to the voice vlans.  The CCA will place the correct security on the interfaces but if you change the IP address on the VLANs from the CLI...  (maybe other places) the access-lists are going to block traffic that needs to be allowed.


I bet the access-lists are blocking something here..  I have personally seen it a bunch of times...  (I have been right before!)


If you look at your configuration you will see where the internet interface is using the access-list... leave that one.... but copy all the access-lists to WORDPAD or something and erase all the others temporarily...  and see if it helps...  You can just cut and paste them back in to get them back..... or reboot (if you can) that will place everything back the way it was. (dont save before you reboot or when prompted).  Again this is just for a quick test.

Hi Steven,


What sniffer would you recommend.... I have no real experience in sniffers as anytime I have had issues I always involved the network experts....


I assume I would install it and point it to the ip address of the router or the CUE 10.1.10.1 or are there any other web interfaces I dont know about?


Thanks

I would recommend using wireshark on your own PC.  Make the skype call and see what happens.  You just need to run it while you are making the call.

Hi Steven,


Are you sure I should run the WireShark on my laptop where I am making the calls from and not the server where the SkyStone Software is running?


All that we would capture from my laptop is the skype to skype traffic....


This would not capture the landline to skype or skype to skype inbound to SkyStone to the UC520....


Thanks

Brian,


DId you try removing the access-lists?  Just do this:


no access-list 100

no access-list 102

no access-list 103

no access-list 104


Then try it again....     DONT SAVE... This will at least tell us if an access-list is blocking the voice traffic...

John,


Your a genius....It works.... But here is a cavet... When making calls either from Skype or the fixed line to skype both leave the voicemails and I can pick up...


However; when leaving a vmail from skype to skpe the MWI lights up and I can hit the # key to enter the menu to leave it high priority....


But when calling my "skype in" number and pressing the the # on either my cell phone or office phone i dont get a response and the MWI indicator does not light up even though there is a message waiting which I can pick up.....


Strange....


What access list do I put back in now?


Thanks for all your help.....


BTW my UC520 rebooted itself last night.... Is that normal?


and I have these files on the flash card:



268     326443 Jun 30 2009 08:10:42 +02:00 crashinfo_20090630-061042

The crash is not normal...  I would open a TAC case...


Listen - you have modified the IP subnets and VLAN's with your own numbers.  Somewhere the Access-lists got fat fingered and mistyped.  Apply one of them back in at a time and see which one disables your voice again... then when you find the one, you are going to have to figure out what it wrong with it. It is blocking something.  I dont know which one...  just do some testing...


Also - is there a way you can just do this all over again?   Using the CCA to start it all off and add as many commands using CCA until you have to use CLI?  I would try that. It seems like you may have some typos..  If not, Save the configuration out for safe keeping - open the uc500 in the CCA and remove and replace the firewall... it may help get the correct one in there....  It may help the WMI as well.

Hi John,


Ok, I think its best to start again.... I will format the flash card and get the CCA 2.0.1 to do all the hard work....


Which version should I use 7.0.3 or 7.1.1 ??? Are there any later releases available?


Also before I change it all I tried to switch the default language to UK I think I have all the language packs but the the CCA dont like it for some strange reason?


Are there any best practice docs I could follow before setting it all back up?


Thanks

Hi Guys,


So I spent all weekend re-imaging the UC520 to 7.0.3.... Started all over again and left pretty much everything as factory default.... except for my local LAN IP (10.54.8.***)...


Only to get the exact same results when calls come in they dont drop into voicemail but you get prompted to enter your extension number...


So I entered the CLI code:



config t
voice service voip
no supplementary-service sip moved-temporarily


Which then after a call is made it does drop into vmail as it should however then the vmail aint left so I remove the access lists and then it does work


but now when calling from landline to skype or skype to skype and after the vmail is left if you want to use other options it looks like the it doesnt recognise when you press a key so you dont get prompted to leave an urgent message....


Also after the factory reset of the system when I log into CUE on 10.1.10.1 and try to log in with cisco cisco it dont like it anymore....


I thought this was factory default username and password.... We are nearly there with all the issue....


Thanks


Brian

This is likely due to a DTMF relay negotiation problem. Can you provide a 'debug voip dialpeer' and a "debug ccsip message" for a failed call?


Thanks,


Marcos
