configuring FXO port trunk group

tato386 · ‎08-12-2008

I have a system with 4 FXO ports and I have a total of 16 dial-peers configured for these 4 FXO ports. The 16 works out to 4 dial-peers for each FXO since each dial-peer matches different outbound call types such as local, ld and intl. Can I use a trunk-group to encompass all four FXO ports and then use only 4 dial-peers pointing to the trunk-group? If so, how would I do that?

Thanks,

Diego

Funny thing I noticed when trying this out. I have four voice-ports numbered 0/1/0, 0/1/1, 0/1/2 and 0/1/3. I want to use them from the bottom up so I added trunk-group ABC 1 to 0/1/3, trunk-group ABC 2 to 0/1/2 and so on. If I have an analog line with tone on 0/1/3 it is used first as expected. However, if I have no line on 0/1/3 the system gives me a busy signal?! I thought the failure to get tone on 0/1/3 would cause it to use the next in line which is 0/1/2. Is this normal?
