H323 Gateways and outbound calls

[wrenfroe]

Have 3 vg200's configured with h323 and fxo ports.

Can make 4 outbound calls on first vg200, but after that no more, next vg200 in route group not being used. All three vg's are members on the same group with different order. Using call manager 3.3(2)

Any help would be great!

Hello,

Problem is that with H.323 gateways CM does not have any power to see if the H323 ateway is busy. If you want to use CM RL in RG you should use MSCP protocol to control gateways.

If you want to use different h323 gateways in order just put dial peer on the first router to point to next h323 gateway with preference higher than all FXO ports and the fifth call will be transfered to the next h323 router.

I hope I gave you enough info to solve your problem.

Best regards,

Aleksander

Thanks for clearing up what the problem is!

However, I have not had any luck getting this configured properly, is there a sample config somewhere that demonstrates this? This is the dial peer I have added, but it doesn't work.

Dial-peer voice 5 voip

preference 5

session target ipv4:[ip of next gateway]

Hello,

I did it like that:

dial-peer 5 pots

preference 1

port 0/1/0

destination-pattern 5..

dial-peer 5 pots

preference 5

port 0/1/1

destination-pattern 5..

dial-peer 5 voip

preference 8

session target ipv4:192.168.1.4

destination-pattern 5..

Try also to check the destination patterns like this:

show dialplan number 555

It must show you three dialpeers first with preference 1, then prefernece 5 and last preference 8
