CUCM 10.5.2 Route Group with TOPDOWN Algorithm is using second path once the primary is up

Hi All,

 

For my CUCM Cluster i got 2 sip trunks which are directly talking to the service provider IP address.

I can the patterns using the RL contains one RG which contains 2 devices(SIP Trunk) and the algortihm is TopDown.

We can see if we run the call report the 2 device is using even if the First route is avaliable.

Please let us know your suggestion to fix it.

If you reverse the order in the route group does that change anything?

I want the Top device to take the calls for me and the second device if the first Trunk is full it can accept 150 calls according to the provider.
We didnt try to change the order.

Re: CUCM 10.5.2 Route Group with TOPDOWN Algorithm is using second path once the primary is up

Hi Jonathan,

 

i want the current Primary Trunk to be used for all the calls not the second device so i cannot change it.

Is this issue occuring because i am adding 2 trunk in the device is that casuing the issue.

Where i can see there are ports or device ports itself i mean gateway which is working fine.

Please sugest.

Hi All,

 

Please assist on this.

If 2 Trunks are added as device is RG it will not work as Top Down algorithm properly. Is that any existing bug or is that normal behaviour of the CUCM.

Hi Shinaj,

 

Can you verify your first trunk is working properly? 

Please test each trunk separately and ensure that both trunks are working properly. Then add the trunk and choose the TopDown algorithm.  see if it works?

Had a look and couldn't find anything related to TopDown distribution algorithm on the UCM version.

Hi Shalid,

 

We can see most of the calls going through the first trunk but around 4% calls are going through the second trunk which should not happen. Previously we had only one trunk which is currently the second one which we will use only when the Primary is down in our current scenario.

If we put Trunks in device list is this a known issue.

I can try by removing the secondary trunk and test it.

Hi Shinaj, 

It looks like the route group is working as expected. the top down distribution algorithm, the call manager distributes a call to idle or available members starting from the first idle or available member of a route group to the last idle or available member. 

In order to achieve your requirement, you should try with creating another route group with second sip trunk and assign in the same route list.

RG1-> SIP_Trunk1

RG2-> SIP_Trunk2

RL will have Route group in the order of RG1 and then RG2.

Hi Shalid,

I will work on this and update you.
