I’m newbie with telit module, I just got one for testing VoLTE network, and seems that Voice MO is not working well.
The SIP invite is initiated by The Telit Module correctly and call is established, however if the call duration is more than 30seconds, the module cannot establish a connection to PCSCF in order to send the BYE and release the VoLTE Call.
Note: After the establishment of the Call (200OK/ACK), the socket is released by PCSCF bye sending Fin/ and RST TCP packet to the module.
in QXDM log we can find errors during the transmission go BYE Message:
[5000/ 2] MSG 13:42:31.204011 Data Services/High [PS_Sock_Platform_Socket.cpp 910] Socket::Bind(): Unable to retrieve remote socketPort 44989 in use, cache handle 105 0x790002000928838e84f6fc008e03881304000000bdaf000069000000536f636b65743a3a42696e6428293a20556e61626c6520746f2072657472696576652072656d6f746520736f636b6574506f727420256420696e207573652c2063616368652068616e646c652025640050535f536f636b5f506c6174666f726d5f536f636b65742e63707000 PS_Sock_Platform_Socket.cpp00910 Socket::Bind(): Unable to retrieve remote socketPort 44989 in use, cache handle 105 Telit Serial Diagnostics Interface (COM21)
Is there a way I can upgrade the LE910C4-NF in order to check if there is a version that already solved this issue?
