on the local network, incoming and outgoing calls a work with audio.
The external mobile sip phone is set up as an extension and can dial in and can be dialed out from all extensions in the setting. Just no audio after dial tone and it connects.
when calling from outside the network the phone rings and connects but there is no audio incoming or outgoing on the mobile sip phone.
sip udp port are 25069 instead of 5060 RTP 10000-20000 forwarded to pbx server ip in the router. also to note I have a dynamic IP but it seems to resolve ok in all other conditions and the PBX works well except for this. . If its a NAT issue then how do you set it up on VitalPBX. I gave tied all the codecs but still same issue. But it does seem like a codec issue if I was to guess.
