OpenVPN connection to Elastix failing

[l4telcom]

Ok, so when I was sending you the crts privately, I did notice that they said Signature Algorithm: sha256WithRSAEncryption. I found that the way to change the Signature Algorithm was to modify the openssl-#.#.#.cnf files as follows:
under the [ CA_default ] header change 'default_md = sha256' to 'default_md = sha1'
and under the [ req ] header change 'default_md = sha256' to 'default_md = sha1'

After making those changes, I created all new keys, and now they show Signature Algorithm: sha1WithRSAEncryption. After recreating my tar file to upload to the phone, I was able to get the phone to connect to the VPN. I can register up an extension against the Elastix PBX using the VPN IP 10.8.0.1, but whenever I place test calls, I get a serious delay with audio going from the VoIP phone to the outside call as well as sever audio quality issues. There is no delay or quality issues with the audio from the outside call to the VoIP phone. I have tried adding in the

Code:

nat=yes
externip=xxx.xxx.xxx.xxx
localnet=10.8.0.0/255.255.255.0

but that doesn't seem to resolve the problem. If I try to register the extension by using the public ip of the PBX, I do not get any audio from the to the VoIP phone outside call.
