Call recording


I have FreePBX 2.10.0 with asterisk 1.8.13rc1 , I have added channel h323 with no issues, I noticed that calls sourcing from SIP ext to H323 ext are NOT recorded, but calls sourcing from H323 to SIP are recorded, although calls between SIP extensions are recorded , what could be the issue?

H323 —> SIP calls are recorded
SIP —> SIP calls are recorded
SIP —> H323 not recorded
