Problems using Record() cmd with IAX2/Voicepulse?

I just installed another instance of Asterisk on a new server and want to use IAX only on this server. Currently the server will accept incoming calls from Voicepulse on IAX (codec = GSM only), but we are unable to use the Record() command in asterisk. We just get a “beep” and the system doesn’t record are appear to attempt to record. It just continues to the next statement in the context.

I’ve checked and double-checked file rights, etc. No luck.

Any ideas or suggestions?
