Softgate - Xpressions via SIP Trunk

Hi guys,

Hope someone can assist with issues relating to SIP trunk to Xpressions.
As I'm running Softgates cannot use H323. H323 only for physical STMI's.

Currently I'm using NETRTE for routing to Xpressions and I'll post my sample config here.
The issue I have is, my SIP phones would initiate a INVITE to their respective vSTMI gateway and that INVITE gets stuck there. It never passes onto the vSTMI gateway responsible for trunking to Xpressions.
When you look at the capture, the PHONE is the one imitating CANCEL message... weird.

As I have one OpenScape Access and one vSoftgate I tried moving the STMI gateway between the two just in case makes any difference.
Xpressions is setup with the SIP stack and has the extensions and scripts for guest/direct/callback access assigned.
Locks in a TCP socket for SIP successfully.
I can telnet both the vSTMI and Xpressions on port 5060.

I have a weird feeling that this is simply not made to work.
It is a complete disaster....

Hi,
Has it been confirmed that 'H323 only for physical STMI's.'?
Have you submitted any tickets to Unify ?

I'm still trying to learn about this kind of network analysis, so I will ask - what tool(s) do you use to collect that data and get it displayed in frames like that? In my situation I'm trying to troubleshoot a lost packets / Bad IP Quality issue that seems to be only at one site, but no one will acknowledge it exists because SolarWinds says everything is fine and happy. It might be for the PCs, but not the phones....

And then I will add my 2 cents worth to your question: I have limited experience with SIP, but I don't think it's the SIP - I think it is a permission problem. One side or the other, or both, don't have the right permissions to do everything on that SIP trunk. It might be the STMI board config, trunk config / COT/COP, class of service, LCR class of service... Maybe the softgate/4K knows how to say "Forbidden" but the Xpressions doesn't and just drops the call (CANCEL)... Just a few random ideas to throw out there that might kick off some ideas.

That applies for both vSoftgate and OSA modules.

@donb01 THanks for your tips I'll surely go through the config again. From a tools perspective, once you go virtual it is easy. ALl comms go through a single interface (bridge to physical network). Using tcpdump on that interface will give everything. Then you get crafty with wireshark filters to get the info you want. Other from that I use TraceEx for ISDN/4K tracing. You can also use the logs/traces provided by the vHG3500 gateways but they are messy. Also, Xpressions has its own debug console where you can apply filters for SIP for example and get the logs/traces from there.

Thanks. I have wireshark and I have asked it to look at things like traffic between 2 IP addresses or traffic at a gateway board, but most of the stuff is presented in ancient Egyptian hieroglyphics :p Yours was all pretty and well laid out!
