4135 SIP issue on OXE - Not acceptable here (488)

Post by szabogabor84 »

Hello Everyone,

I'm having some challenges when I try to make conference calls using 4135 conference phones on OXE R11.

I have a few 4135 SIP phone setup on OXE R11. When I make a call, the fist call is working fine, when I dial the second number while I put the first call on hold, I get the “Not acceptable here...” message on the screen.

This issue is intermittent, I'm only able to make the second call once or twice in every 10 attempts.


The output of the SIP trace is:

Sep 7 11:05:29: RX 583 bytes Response msg 488/INVITE/cseq=21214 (rdata0x1dfbc4) from UDP 192.168.200.220:5060:

Does anybody have any idea?

Any help much appreciated.

4135 - declared as SIP devise or SIP extension? If your change set type - behaviour the same?

If anyone finds this post with a similar problem, in my case the issue was resolved.

Really was not an issue, I was just performing the conference (or transfer) too fast in the test scenario. If you wait a few seconds (~4s) after the call is established, you can set up transfers or conferences without any issue.

If you compare the same scenario, but performing the transfer from a 8008 for instance, you will find that during the first seconds of the call you actually cannot input any number to perform another call.

I dont know deeply the why´s of this yet, but helped me to solve my issue.

Regards to everybody.
