Hi! I have a group defined to call three extensions. The inbound route uses G729 and I only have one license. When a call comes into FS with a g729 codec chosen, the group call fails with encoding errors. Only one extension in the group supports the g729 codec. 2010-07-01 20:32:17.685087 [ERR] mod_com_g729.c:142 DECODER CREATE FAILED - 0xb6738248 (nil) 2010-07-01 20:32:17.686085 [ERR] switch_core_io.c:352 Codec G.729 decoder error! Is this because FS is trying to set up 3 channels on the b-leg with g729? I thought by activating late-negotiation this might work. No luck. I thought by creating a specific dialplan in the users setting it might work. I couldn't find the correct format. Would this work? <param name="dial-string" value="{absolute_codec_string=GSM}{presence_id=${dialed_user}@${dialed_domain}}${sofia_contact(${dialed_user}@${dialed_domain})}"/> Is there a way I can get this to work, or do I need to force the inbound call to use another codec? Thanks for your help
