How Can RMX2000 support SIP INFO

Hey guys.I think something wrong with my RMX2000.When RMX call to 3rd party  system,remote send a SIP INFO message and RMX reply '488 not acceptable here',then RMX can not send DTMF signal ,when IVR timeout the session close by remote.


How can RMX support SIP INFO ,or send RFC2833 DTMF to remote?

Re: How Can RMX2000 support SIP INFO

Hello @limerez ,


Welcome to the Poly Community.

It would be great to get some basic information like the software version of the RMX and/or DMA.


According to the RMX Admin Guide, it supports both 2976 SIP Info Method and 2833 RTP Payload for DTMF.


Is this only an issue with the 3rd Party? Is this a day one issue or has this only recently started?


As the community is only volunteers if you want to find the root cause a support ticket would be needed.

In order to raise a support ticket, you need to work with your Poly reseller as they may need to do this for you.

End Customers are usually unable to open a ticket directly with Poly support. Available End User Poly services offerings are detailed here


Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Re: How Can RMX2000 support SIP INFO

Thank you  SteffenBaierUK.

DMA version is 10.6.0 and IP addr,RMX2000 version is 7.7.0 and signal IP addr

It's a new requirements with connect 3rd party  but  look like complicated problem now,the  Supplier Engineer  also can't solve the problem.

I  tried to add some Syetem Flag on RMX2000,but it was also a failure,just like in the attachment.

Any other way here?
