Hi,
I have an SL2100 with 6 remote IP phones connected via a VPN. Calls into extensions at the site with the pbx work fine, as do external calls inbound and outbound
What we cannot do is make calls between extensions at the remote site, if we dial the extension we here the ringing dialtone but then when the extension picks up there is no audio and after 10 seconds the call is ended and the IP phone displays hang up
This is only happening on the internal calls between the extensions at the remote site,
In terms of the config for the phones they have
SIP 1st Server Address: internal IP of pbx Access mode: Normal SIP 1st Server Port 5080 NAT traverse Mode: Dynamic WAN Mate IP: Internal IP of the PBX WAN Mate Port: 5080
Could anybody let me know what may be going wrong?
