sipp can not process calls with same call-id but different From tag

[kadabusha]

Hi. Checked with latest released version - was not able to make 3.7 working on FreeBSD unfortunately.

Current behavior: UAS does not recognize second INVITE with same call-id as previous as new call. UAC crashes to coredump on second call.

RFC3261:

Call-ID contains a globally unique identifier for this call,
   generated by the combination of a random string and the softphone's
   host name or IP address.  The combination of the To tag, From tag,
   and Call-ID completely defines a peer-to-peer SIP relationship
   between Alice and Bob and is referred to as a dialog.

How to reproduce:

[test@123 /var/tmp/sipp]$ ./sipp -v | head -n2
 SIPp v3.6.1-TLS-SCTP-PCAP-RTPSTREAM.
[test@123 /var/tmp/sipp]$ ./sipp -i 10.133.30.2 -p 5060 -sn uas -trace_msg -trace_err
[test@123 /var/tmp/sipp]$ ./sipp 10.133.30.2 -s 123 -i 10.133.30.2 -p 5069 -m 2 -r 1 -cid_str test123 -trace_msg -trace_err
[test@123 /var/tmp/sipp]$ sudo /usr/local/bin/gdb82 /var/tmp/sipp/sipp /var/tmp/sipp.9487.core
