Mitel Sip Lines Help

[SUSD]

3300 MXe 2-Clustered Rel 4.2 / 10.2.0.26_2  EMB-VM 6-SX200 10-ASU

We have a Sip trunk/6lines for a Vocera comms system, which has been functioning long before I started working here. I don't know much about Sips, but. The Vocera system is not working. I dial the extension for Vocera, the connection seems to be active and after 30 seconds, times out and I get busy indication. So I believe Vocera is not answering. Vocera people say there system is fine.

I do Sip Stats All, I call the extension with 2 phones, Sip Stats All shows 2 active calls. So its my belief that the Mitel is handling the calls ok?

I'm just wondering if there is more I can check to verify the Mitel side is good ?

Thanks.

sip link state all in maintenance

Or make a change in the SIP Peer profile and then change it back will restart the sip service for that profile

[SUSD]

v2win,

I tried changing options in profile, no joy there.  I tried Sip link state all, I get this response:

"There are 1 SIP link(s) programmed.
Link     Vocera state is       IN SERVICE (link down count 21)"

So this shows In Service, but link down count 21, can you give me any info on what this means ?

Thanks.

More -

This Sip programming also has a DID range for CPN Substitution.   6xxx to 705 xxx xxxx

I can dial the 705 xxx xxxx number direct and it answers. But again, my system just times out when I dial the 6xxx and tells me Busy instead?


Thanks.

What are the actual DID ranges on the SIP trunks?

[SUSD]

The DID Range for Sub is  6742  to 705 xxx xxxx,   so just the one DID

but in the Peer Profile

Maximum Simultaneous Calls is 6

[x-man]

so you dial 6742 and that translates to to 705 xxx xxxx (I assume this ARS to get between systems? or is that done by networking?) and you can make 6 concurrent calls using just the one number?

[SUSD]

There is an ARS Route   14 Sip Trunk    Sip Peer = Vocera    COR 1   Dig Mod 1  Compression Off

I have made 4 calls at once to the 6742 extension and they all time out with Busy.

[x-man]

and what uses that route for calls?

[SUSD]

Ok,

If I'm reading this right.  ARS Route 14 is using SIP Medium for Vocera ?

[x-man]

What does digit mod 14 say ?

[SUSD]

Attached Digit Mod

[x-man]

Is ARS route 14 referenced in ARS digits dialled at all?

[SUSD]

Yes, here 6742

[x-man]

So somewhere there is programming that translate 6742 to 705 xxx xxxx and you can use it six times. So unless you can find that programming my guess is that its missing and hence when you dial 6742 it just goes to busy because the call cannot complete. That would make sense of the route so i would suspect that digit mod 14 should absorb 4 and insert 705 xxx xxxx. That way every time you dial 6742 it will route to the ars digits dial which will reference dm14 which will absorb 6742 and replace with 705 xxx xxxx. At trhe moment you dial 6742 and it references that in ARS but digit mod 14 just tells it not to absorb any digits and hence the call fails.

At least I think it should
