Wireless Access

Hello everyone,
I'm running into an issue with a softphone (SIP) on Aruba Instant 503 APs. The problem is that the softphone won't stay registered with the gateway. Funny thing is, when I test it on other access points from different vendors, it works just fine.

I've already played around with several Instant settings - including SIP firewall and some secure options - but no luck so far.

Anyone got ideas on what else I could try?

What version of software?

The version is 8.12.0.2.

Any chance to test it with 8.12.0.6 or 8.13.0.1?

Looks like some session timeout or similar issue,

Best, Gorazd

The customer's environment is somewhat complex, as there are robots using the wireless network 24 hours a day. Since I did not find anything related to a fix for this issue in the release notes, I would prefer not to request a system reboot without a valid reason.
I would like to ensure that I have exhausted all possible options before reaching that point.
Is there any specific configuration or best practice that should be applied on Aruba Instant for this type of solution with softphones?

Hello,

What is the Register/keep-alive interval on the softphone side in seconds?
Also, can you capture pcap for ports tcp/5061 and udp/5060 on the device?
When you capture pcap, you can check the following:
Is REGISTER going from the client?
Is the server responding with 200 OK?

You can also check the values between the SIP server and the client with this command:
show datapath session | include <client ip>
