Re: Max Phones exceeded - ISR4351

wilsonsant · ‎03-27-2018

Hi Guys,

My Customer have a solution with CUCM 10.5.2 and in the remote site there is a gateway ISR 4351. Today, this remote site lost the connection with Main Site, then any IP Phone go to SRST Mode, but, any phones presented the message: "Max Phone exceeded" in display. In read any posts, but, not stay clear for me if this problem is related the configuration, hardware resources or license.

Could help me, please,

Thanks,

Regards,

Wilson

Can you share "show run" and "show license all" from the router ?

Your SCCP and SIP CME are configured to support 40 IP Phones each. This can also be seen from the license in-use output -

How many phones did not register vs total available phones ? Phones were SIP or SCCP or a mix of both ?

wilsonsant · ‎03-28-2018

Hi Nipun,

In the site we have 53 IP Phones, all are SIP. About the IP Phones not registered when entered in fallback mode, I don´t have this information. 40 is the maximum IP Phone that will to register when the site enter in Fallback mode? This is a hardware limitation for this specific gateway model or is possible to configure more IP Phones with hardware/software version?

Thanks,

Wilson

R0g22 · ‎03-28-2018

40 is not the hardware limitation. ISR 4351 will support I believe around 250 IP phones, SIP and SCCP included. You need to configure a higher value for max-pools under voice register global in order to accommodate all 53 phones.
