messages in the same call setup. When we receive the 180 we present
ring back to the phone, but when we receive the 183 we get confused and

the ring back to be played from the network.</span></font></div><div style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: 'Times New Roman';"><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;"> </span></font></div>

Metaswitch the configuration knob to correct this is “Superfluous 18x
