[Spce-user] mr5.1.1 dropping calls

[Henk]

Hello,

After upgrading to mr5.1.1 from 5.0.1 I have problems with calls being 
dropped after about 1 minute, especially calls to an asterisk box.
A capture revealed that ACKs are missing. In the debug log I found lines 
about failed transaction matching, which may be relevant.
The asterisk extension has default settings with only e164_to_ruri 
enabled.in subscriber preferences.

Debug log:
