When Cisco Unity Express users try to check their messages remotely the message is garbled and they can't really hear it

I have a CME/CUE configured on a cisco 2811 Router.  I have two offices that share this CME/CUE.  Office 1 is in the same room as the 2811 router which has a FXO card with 3 analog phone in it.  Users in Office 1 do not have any problems.

Office2 users have their own VOICE Gateway router (Cisco 1760)with an FXO card because they have their own phone lines, but their IP phones are configured on the CME in office1.  When office2 users try to check their voicemails REMOTELY (like from a cell phone) they can hear the auto attendant perfectly, but when the message plays they CAN'T hear it and its all garbled, but if you listen to the message on the IP phone itself you can hear the message fine.  I've had the phone lines tested and they are good.  There are only two phone lines in office2.  

Office 1 user don't have a problem at all when listening to their messages remotely.

Ok so when people from office 1 check thier voice mail from thier cell phone they have no issues? Its only the 2 people at Office 2 that have a problem?  Its only on thier cell phones that they have an issue? Do they each have the same cell phone provider?   Have you heard the messages when garbled through thier phone?   Can you call into thier voicemail with your cell phone and get the same issue?

Thanks.
Yes people in Office1 have no issues checking their voicemail via a cell phone or other type of phone.

Yes only the two people at Office2 have problems checking their voicemail remotely.  They can check their messages on the IP Phone itself with no problem.

Office 1 and Office 2 both have the same cell provider, I've also tried it with my cell phone, and I get the same result.  The messages are gargled and you can't really heart them from office 2.

If I call their voicemail from my cell I get the same thing.

Ok this is weird.  If I leave an internal message (IP phone to IP phone) and check it remotely I can hear it fine.  But if I leave a message from an external phone (cell, home, etc) and then dial in to check my message remotely is very garbled and I can't really hear anything.

This is how my users check their voicemails from the outside:

They call into their office, when the AutoAttendant picks up I hit option 7.  It asked them to enter their ID which is their extension, it then asks them for thier password.  Users from office2 can hear this part fine, but when the messages starts its garbled and you can't really hear it.

Office 1 can hear their messages remotely fine.

Yes the CME/CUE is located at office1.  
 
Office2 has their own Voice Gateway Router because they have their own phone lines, but the IP phones and voicemail box's are configured the CME/CUE in office1

When you access voicemail from outside for Office2 users, do you dial into Office2 FXO or Office1 FXO?
0
 
denver218Author Commented:
Office 2 users normally dial into Office2 FXO, but I also tried it from Office1 FXO and got the same thing

Pro4iaCommented:
Can you dial in from outside to Office1 FXO, leave a message on an Office2 user and check the voicemail?
0
 
denver218Author Commented:
If I dial in from outside to the Office1 FXO, leave a message and then check it, it is alot clearer.

If I dial in from the outside to Office2 FXO and leave a message and then check it, its really garbled and you can't bearly hear.  Wierd

What would cause that?

Its just thier voice mail right if they call from outside into the office does the person in the office complain of garbling?  Can you test this if you havent already.

What codec are you using for calls?  Are you sure theres not a mismatch anywhere.  Have you verified configs for office 2? Any way you can post that config up?  DO you have an analog phone you can hook to the card and check your messages see if its still garbled?

Sorry for not getting back sooner, I was out of the office for a couple days.

I am using G7.11 codec.  I do have an analog phone.  Do you mean to plug the analog phone into the FXO card where my phone lines are plugged in to?  Would that work?  I

I don't have any FXO ports of the Voice Gateway to plug in an analog phone

Attached are my configs:  Office1 users have no problems.  Office2 users have problems when trying to listen to their voicemails remotely.  On Office 2 configs I'm only using Voice-port 0/0 and 0/1.  They only have 2 phone lines.  Everything works well for office2 other that remotely checking messages, which sound very garbled.  Please let me know if you see a problem.  Thanks.

You are using SIP to H323.....The only thing that pops out at me is in the Office 2 config you only have allow-connections sip to h323 you also need allow-connection h323 to sip check that to see if that work if not I will look more maybe another expert can comment also.

voipmanCommented:
Yes SCCP on the phones but you're using SIP and H323 to establish the calls I can see it in your configs.  I dont think that command will fix it but you should have it in there since you are using them.

Ok, this is weird.  On the office2 gateway router I had the following route statement:
ip route 0.0.0.0 0.0.0.0 172.16.0.1

This is my default gateway in Office 1.  Well I took that route statement out and added the following route statement:
ip route 0.0.0.0 0.0.0.0 172.16.2.1 (Which is the CME in office 1)

I then left a test message and was able to check it externally via my cell phone perfectly.  I did this several times and it worked every time.  It doesn't make any sense because everything worked fine other that checking messages remotely.  I am going to let it go for a day or two just to make sure this was the fix.

denver218Author Commented:
Cisco thought that the fix was a weird one also, but told be to let it go a few days.  Its is still working fine today, so hopefully changing that route statement fixed it for good.  This was a "makes no sense solution" but I guess it works for now.  Thanks for all your help.
