One-way Audio with canreinvite=yes

Hi guys,

When I connect my linksys SPA 901 with the option “canreinvite=yes” I just have a one way audio from the phone to the called person.

When I set “canreinte=no” It’s working fine.

When I use my softphone with exactly the same configuration than my IP phone, with canreinvite=yes it works well and the RTP stream goes directly from my phone to the called as expected.

the nat is set to “yes” also…

Is my phone not able to reinvite ? do you know any phone able to reinvite ?

Thank you very much!
