<div>I have a issue with the A10Xe sangoma digital cards, using the following versions of WANPIPE 7.0.23, DAHDI 2.11.1, OpenR2 1.3.3 and Asterisk certified 13.13-cert9, on CentOS 7, to receive calls with CAS - MFC/R2 signaling on E1 trunks from Telefónica de<br>
Argentina.</div>
<div>The phenomenon is that the incoming calls in some cases are handled correctly but in others the same call enters into two channels simultaneously, and a few milliseconds later are released from the TELCO without apparently reaching to exchange R2 signals.</div>
<div><br>
