Assertion@1471 Hal_Audio_RtpRx

[Gkanda80]

Hi Everybody, We have 32 Mitel 5320 phones. Somehow they are randomly restarting with error message ("Assertion@1471 Hal_Audio_RtpRx"  "Assertion Failed Hal_Audio_RtpRx@1471 udpSocket!= NET_SOCKET_ERROR").

can somebody help how to resolve this issue?

[ralph]

are they failing on transfer or on answering the call?  or are they sitting idle and then failing?

They restarting when making calls or some time answering calls. It is happening randomly to all phones.

Are they talking to a Mitel 5000 system or some sort of SIP service?

Looks like a network error of some kind, could well be something taking up a lot of bandwidth (broadcast storm) so the phones cant communicate with whatever is the server.

We had similar once when someone added a printer to the network and gave it the same fixed IP as the MBG internal address. The problem was only there when the printer was in use....

Look at your data switches and router.  Turn off ICMP redirects.
I've seen similar things multiple times on the 3300 but I'd bet it applies here to.
For some reason on an answer, call or transfer one of the network devices will send an ICMP redirect that will cause the exact problem you describe.   (Note: this shouldn't happen on latest version of software)

We got Draytech router and i couldn't fine disable ICMP redirect option in this router. So would you recon we have to change router. Our network is flat network and we only have 30 phones in total.

[ralph]

I wouldn't think on a flat network that would be the case then.   What are you using for your data switch?
