Hi,

I have an installation of IP Office R7 (Version 7.0 232702), and I recently installed the "Softphone" that came with the admin CD. I can successfully login to the system and view extensions, etc. The problem is whenever I make a call or receive a call, there is no audio. Any suggestions? I've tried both Windows 7 and Windows XP.

Thanks,
John
 
Firewall on the PC, Firewall in the local network, Firewall on the remote site, bad IP routing for real time UDP traffic, and another 1000 reasons why it does not work.
It is up to you to start thinking how it works, were can it be broken and start checking the breakpoints.
For us it is in no way possible to help you out.

Well that's reassuring... No client firewall or antivirus, so that can't be it.
 
if it is not antivirus or firewall then it is almost certainly a routing issue.

switching off Direct Media Path will prove this (It is not a "Fix" the fix is to correct your data network)

the standard process for resolving VoIP issues is:-

1: Check/correct Data Network
2: if fault still present goto 1

A Maintenance contract is essential, not a Luxury.
Do things on the cheap & it will cost you dear
 
The network is as follows:

SonicWall Firewall Interface X0, with VLAN sub-interfaces. The LAN VLAN is 10.1.1.0/24, the Voice VLAN is 10.2.1.0/22.

1. A user directly connected to the LAN VLAN via a Cisco switch connected to X0 can ping 10.2.1.0/22 just fine, and the Softphone application runs (just no audio, only ringtones and dial strings). IP Office Manager works just fine.
2. A user terminated on a VPN connection that places them on the 10.2.1.0/22 network can complete all the same activities as the former example.

Thanks,
John
 
SonicWall Firewall

99% sure this is your culprit!

turn off the SIP ALG - and I bet it will work

Alternatively - use a "router on a stick" approach to intervlan routing. Personally I wouldn't route intervaln traffic through a firewall - unless there is a very good reason (and you haven't yet provided one)

Please stop trolling, it's not productive. If you have nothing to put on the table to assist, don't comment. I'd rather not hear about children and dishes, this is a technical forum.

intrigrant is no troll! His response to your first post was bang on - you'd provided no information. The response to that was a generic one and tbh 45% of the time is a resolution

next - you say it isn't firewall or AV - fair enough, but still no further details...

As soon as the details are there - tghe problem becomes obvious


AS for trolling - I think the boot is elsewhere!

I have always wished that my computer would be as easy to use as my telephone.
My wish has come true. I no longer know how to use my telephone.
 
If Intrigrant says that something then take that for granted.
Ofcourse he is not always right but most of the times he is :)


BAZINGA!

I'm not insane, my mother had me tested!

 
Thanks for the replies. Here are the "VoIP" settings on the SonicWall firewall (not my choice to use it, by the way - I'd much prefer an ASA5505 in this install):

Well that didn't work... Here are the settings (all unchecked):

Keep in mind, this is an H323 instance/extension, I don't believe my configuration of IP Office 500 supports SIP.

####

Enable consistent NAT

SIP Settings

Enable SIP Transformations
Permit non-SIP packets on signaling port
Enable SIP Back-to-Back User Agent (B2BUA) support
SIP Signaling inactivity time out (seconds):
SIP Media inactivity time out (seconds):
Additional SIP signaling port (UDP) for transformations (optional):

H.323 Settings

Enable H.323 Transformations
Only accept incoming calls from Gatekeeper
Enable LDAP ILS Support
H.323 Signaling/Media inactivity time out (seconds):
Default WAN/DMZ Gatekeeper IP Address
 
@nebj00la, I was referring to children because the way you ask a question is childish and not answerable in a fashioned way.
And as a matter of Fact, Trolls are amongst my favorite creatures just like Dwarfs and Golems, a pitty they are not real.

But although I think to know what your problem is I will let you struggle and laugh my trollish laugh....

>Keep in mind, this is an H323 instance/extension

No it isn't

Softphone is SIP based

OP, put the PC running softphone in the same VLAN as the system or even directly connect, I will bet it works fine then put it back in the other VLAN that pushes it through your Sonicwall, I will bet it stops again but you know where the issue is :)
