SPA9000 dropping incoming calls within a few seconds, immediate callback holds fast.

Unanswered Question
Jul 22nd, 2009

We have a SPA9000, current firmware, SPA962 and SPA942 setup...

Essentially what seems to be happening is that incoming calls are dropping within a few seconds very commonly and usually when the caller tries again the call will stick.  I've also noted from my cellphone that calls drop very frequently on transfer to voicemail to our SPA400.

Outgoing calls are just peachy.

Now, i'll note we've used the WAN interface on the SPA9000, as our internet provider is actually supplying us with the SIP trunks over fiber to our location.  We have a static external IP assigned to the WAN interface on the router and a static IP assigned for our internal LAN.


We consistently have 10-15mbps up AND downstream and they have QOS configured through their equipment.

I'm hoping to eliminate the SPA9000 as the problem and then take it to my ISP/voip-provider for troubleshooting the SIP trunks.

I can post debug info and will collect some today.

Any ideas would be helpful!

UPDATE:


Here's the debug from a two-call sequence.  First call dropped within seconds of pickup, second was solid to completion.

Hi ssijschneider,

The INTERNET port on the SPA9000 is the recommended way to connect the device, so this should not present any problems...

I'm not clear what you mean by: "We have a static external IP assigned to the WAN interface on the router and a static IP assigned for our internal LAN."

Are you saying that you have configured and are using the SPA9000's ETHERNET port?

If so, this could present all types of problems, depending on traffic through the SPA9000's router.

Our best practices recommend connecting only the SPA9000's INTERNET port, as described in the Installation Guides [Wizard and web-ui]: https://www.myciscocommunity.com/docs/DOC-1751

Is this a new installation? If so, consider using the Setup Wizard to properly configure the system: https://www.myciscocommunity.com/docs/DOC-8126

I looked through the log that you posted, but don't see anything obvious. Can you capture a Wireshark trace please?

Regards,

Patrick

Patrick,

Since your last post, i've reconfigured the setup to run through the internet port on the SPA9000 as recommended.  We're up and running with the same issue, and i've pretty conclusively eliminated my LAN as the issue as all LVS devices are 100mb full duplex to an SRW2024 and it's showing 0 collisions, good traffic, etc.

Here's a wireshark trace of the same caller dropping repeatedly:

Thanks for your help!

Hi ssijschneider,

Looking through the trace, I don't see anything obvious.

I'm going to escalate this to support. [this is not official support, so feel free to contact official support channels if your need is urgent]

I need the following please:

1. Current config from SPA9000: https://supportforums.cisco.com/docs/DOC-9861

2. Current config from SPA400: https://supportforums.cisco.com/docs/DOC-9865

3. Current config from a phone displaying this problem: https://supportforums.cisco.com/docs/DOC-9933

4. syslog log with debug from each device:
https://supportforums.cisco.com/docs/DOC-9934

https://supportforums.cisco.com/docs/DOC-9863

https://supportforums.cisco.com/docs/DOC-9864

5. Wireshark trace of events.

Basically I need you to:

1. get everything ready, start the Wireshark trace, start the syslog server, and then make several calls.

2. write a description of what happens and when it happens so it's easy to find in the log files.

Thanks,

Patrick

Hello - I'm having the same problem. Probably started up about 3 months ago, and I don't know why.

Seems like the first call for the day gets cut off after a few seconds, but then when they call back, it stays on the line fine.

Does anyone have any results in fixing this?

Thanks!
