[Freeswitch-users] SIP info not relayed when call is on hold

[FX Geneste]

Hello guys,

     I am trying to exchange SIP info message (dtmf signal) between 
Phone 1 and Freeswitch B as follows :

Phone 1 <----> Freeswitch A  <-----> Freeswitch B

     Everything works fine except when the call leg between Freeswitch A 
and B is on hold (for instance, the Freeswitch A has received an INVITE 
with "a=sendonly" from Freeswitch B). In this case, Freeswitch A 
correctly receive the SIP INFO message from Phone 1, but does not 
transfert it to Freeswitch B (as it does normally without call on hold).

     I do not see any errors or warnings in freeswitch logs, simply, 
freeswitch A is not sending the SIP info to freeswitch B. I'm using fs 
v1.10.2.

     Have any of you ever had this kind of needs or know how to solve it ?

Regards,

FX
