Release of Version 3.13.0
This release contains two changes. The first is in opal 3.10.13 which fixes a Cisco CUBE bug where it starts with sequence number 32768 instead of the required 0 in UDPTL T.38 packets. The second fixes missing DTMF method in SDP on Invite. This problem caused Alcatel systems to not allow us to make a call.
This release also contains a buffer overflow fix.
This release requires opal 3.10.13 and ptlib 2.10.13 from my repositories.
