VOIP calls without voice
-
Hello,
Since I implemented pfsense in our network, we have the following problem:
2 SIP phone are able to establish a coll on a remote site but, they have no voice.
Local site to remote site = no problemI have no idea what is wrong. (the pfsense is currently only in our local site)
Anyone here that can give me some info ?
Thanks,
Sven -
What was in front your network before pfsense?
Are you double natting traffic?
network -> pfsense -> dsl router -> internet
