UDP to TCP conversion for Speech Server

[KarlD]

1. Brekeke Product Name and version: 2.2.1.6
2. Java version: 6
3. OS type and the version: Windows XP
4. UA (phone), gateway or other hardware/software involved:
Inbound SIP, Netgear firewall
5. Select your network pattern from http://www.brekeke-sip.com/bbs/network/networkpatterns.html : 8
6. Your problem:

I have a simple dial plan rule that sends all SIP invitations to Speech Server:

Matching Patterns

$request = ^INVITE

DeployPatterns
To=sip:99@192.168.2.201

I have tried using $transport=TCP and ';transport=tcp' at the end of the To address but neither option does the conversion. wireshark shows the call being delivered to the IP address but it is not processed.

When using $transport no Active session is created, when using transport= an Active session is created but the detail shows that the outgoing message is still UDP.

When using $transport, the call shows as Result Failure, Error 302. When using transport=, the call shows as Result Cancel, Error 487.

I've also tried &net.sip.transport.follow.request = true with both options but this made no difference.

All the Configurations SIP TCP options are set on (as default in 2.2).

Can someone please let me know what I'm missing...

Hi,

Is the Speech Server working on 192.168.2.201 port 5060?


> When using $transport, the call shows as Result Failure, Error 302.

Can you paste the 302 response packet here?

Thanks for the reply, is this what you wanted...

Hi..

Unfortunately, your pasted information doesn't include a 302 packet image you mentioned...

Can you paste SIP packets including 302?

[SOSAGES]

Hi,

i have a speech server setup that i wish to be able to call using my VOIP phone.

To do this i am currently using PBXNSIP but as thats very expensive for my needs i am wondering can anyone provide some information on how to setup breke sip server to work with speech server?

I looked at the documentaion and that mentioned Office Comms Server but im just using SPeech server

Thanks in advance.
(sorry to hijack your post)

[lakeview]

Hi SOSAGES,

Try the DialPlan below.

Matching Patterns

$request = ^INVITE $registered = false $outbound = false To = sip:0(.+)@

Deploy Patterns

$transport = TCP $auth = false &net.sip.transport.follow.request = true To = sip:+%1@<SPEECH-SERVER-IP>

If a call has the prefix "0", it will be forwarded to the SPEECH-SERVER's IP address.


>> (sorry to hijack your post)

You need to create new topic.. it is good idea.

[SOSAGES]

hi lakeview, thanks for the help.

the line:
&net.sip.transport.follow.request = true

displays as a red line once its been entered and ok'd
i assume red is bad?

[lakeview]

Hi SOSAGES,

>> i assume red is bad?

you don't have to care about it.
