I am using Axon (version 1.09) with 15 extensions (primarily Grandstream model GXP2000 and Grandstream Budgetone 102), a few Linksys SP3102's (for outgoing faxes) and Linksys PAP2T units (to regular old phone sets).
I am having some trouble with calls dropping and hearing one side of the conversation, even if only one call is in progress. I understand this is likely resolved with port forwarding on my router. My confusion is with exactly what ports should be forwarded.
I have a Linksys RV082 router, which has port forwarding (5060-5099 and 8000-8050) to my Axon computer located at 10.10.10.125. By the way, this router also allows me to create rules for bandwidth management, whereby I can establish a minimum of 100 kb of upstream and 100 kb of downstream bandwidth is reserved for these ports.
My confusion arises with TCP versus RTP and UDP.
In Axon I have Sip port set to 5060, and the RTP port set to 8000. Are both these ports UDP?
My delimma is: When I setup port forwarding, do I use the following rules?
UDP 5060-5099 to 10.10.10.125
UDP 8000-8050 to 10.10.10.125
Do I also need to setup any TCP port forwarding such as?
TCP 5060-5099 to 10.10.10.125
TCP 8000-8050 to 10.10.10.125
If there are more port forwarding rules, which I need, I am unaware of them; and I would appreciate any additional guidance.
Thanks,
Henry
