Multiple codecs allowed for extensions?

Ok… quick question in freepbx for extensions I can put in a codec for allow and disallow and it goes into the sip_additional.conf…

What is the correct syntax to put in multiple codecs… say like


Are the codecs seperated by a space? a “,”? What is the correct way here to get asterisk to recogonize the multiple codecs allowed on a single “allow” line?

If you’re talking about specifically in the allow field in the extension in FreePBX, you use an ampersand:

allow g729&ulaw&gsm
