Unable to Dial Long Distance numbers fromCIPC(SCCP) Deskphone(SIP)work

chaitusite — Wed, 26 Jan 2022 07:25:31 GMT

Unable to dial some numbers from CIPC (SCCP) phone, but Desk Phone(SIP) calls are working with Same CSS and Device pool.

CUCM Version:11.5.1.13901-3,

call flow:

CIPC(SCCP)--->CUCM--->Gateway(H.323)--->PSTN(PRI)--->Notworking

Desk Phone(SIP)--->CUCM--->Gateway(H.323)--->PSTN(PRI)--->Working

Thanks,

Krishna

What have you already troubleshooted?

Have you compared a working call with a non-working call?

You cannot just scream for help, without doing first steps of troubleshooting on your own.

Also, without any logs, nobody can help either.

Is the non-working call hitting the GW? If not, then probably the problem is on CUCM side.

If it is hitting the GW, than compare a working and a non-working call. See, if it number formats are the same, the calls using the same dial-peers, ...

I am getting the error on CIPC "High Traffic Try again Later"

Re: Unable to Dial Long Distance numbers fromCIPC(SCCP) Deskphone(SIP)

chaitusite — Wed, 26 Jan 2022 08:31:34 GMT

both the phones are having same configuration CSS, Device Pool but still CIPC all is not working , checked DNA looks fine

Again:

What have you already troubleshooted?

Have you compared the logs of a working call with a non-working call? (RTMT logs, GW logs, ...)

And also: if you would have searched the internet for "High Traffic Try again Later", you would have find tons of old cisco community threads regarding this error. Maybe one of those could have helped, before opening another post.

The forum is not here for you to sit back and let others do your job.

Please post the output from from debug voip ccapi inout and debug isdn q931 from you gateway for both a working and non working call.

chaitusite — Wed, 26 Jan 2022 09:40:51 GMT

Hi Roger,

Since it is a remote site, now i have made only test call from CIPC and attaching the GW Debug, i will post Working one once i had some one at site.

Hi,

Difficult to say for sure without any logs provided of your failed call.
If DNA is fine, the next stage is to focus your troubleshooting on the gateway I would say.
Also as @b.winter said, there are a few hits on the error message "High Traffic try again later" and they more or less match the issue you describe.

b.winter — Wed, 26 Jan 2022 09:59:08 GMT

Nobody can give you anything, without you delivering the information.

By just describing symptoms and not delivering any logs / configs, nobody can't do anything and won't give any suggestions.

Nobody can read anybody's mind...

That's why I asked for logs...

Like @Roger Kallberg said, please also include debug isdn q931 in your logs.

Re: Unable to Dial Long Distance numbers fromCIPC(SCCP) Deskphone(SIP)

b.winter — Wed, 26 Jan 2022 10:58:11 GMT

As far as I see it:

Router tries to route the call via dial-peer 23 --> but gets Cause Code 1 back (unallocated / unassigned number)

Router tries again to route the call via dial-peer 22 --> but gets again Cause Code 1 back (unallocated / unassigned number)

Maybe you sending it down the wrong dial-peer, or sending the numbers in wrong format, ...

Router tries again to route the call via dial-peer 10 --> gets Cause Code 16 back (normal call clearing)

Could you please also post the config of the router? (strip of any usernames / passwords)

You could try to remote control a phone at the site with this crafty little tool that the one and only @Anthony Holloway so kindly has made available.

Kindly share the debug isdn q931 outputs while testing a non working calls. That also help us.

i have collected debugs from the gateway for working and non working calls,

Asper the debugs,

can you share the config for.

Taking your dial-peer config, it covers the findings about your the call logs.

Since your called number begins with 4, it will use the CUCM dial-peers as outgoing dial-peers first.

Maybe you should re-configure your dial-plan, something like this:

Assuming, that you send all called numbers from CUCM to the GW starting with 9.

Absolutely sound advice, but I would suggest the following alterations to your configuration suggestion.

@chaitusite Based on the shared configuration and debugs it looks like you have a loop in your call setup and this is caused by that you have overlaps between the match on your dial peers. This is not a good state to have. As advised by @b.winter suggest that you alter the way you send calls from CM to your VGW and how your match the calls outbound to PSTN. If you use a break out code, for example 9, the easist is to keep that in the called number as the call is passed from CM to the gateway. Then in the gateway you use this to match the call going to PSTN and consume that on it's way out to the service provider. There are many ways to achieve this, the simplest is to let the default function of POTS dial peers to consume any explicitly matched digits to be stripped. If you don't want that or have other needs for how to modify the called number you can do this with voice translation rules. Let us know you preference and we can lend you a hand with that part as well.

AFAIKT none of the suggested changes has been implemented. What is you intent with posting your configuration?
