Hi guys,
I've discovered that Gigatset and Yealink IP cordless send SIP INFO in a wrong way, according to SDP RFC.
If I press 4, I get on SDP
Signal=4\r\n
Duration=100
While should be
Signal=4\r\n
Duration=100\r\n
Freeswitch (1.4.23) answers with 400 Bad Request. I wonder if there's something like a NDLB params to accept this format, based on SDP Content Length.
Thank you
