Getting 4101=Maximum number of trunks

[sunder.J]

We have 3 nodes on ABCF on Hybrid link. Node 2 is integrated with MTW and PSTN PRI-T2 is connected to Node 1. When PSTN call is made from MTW from N2 to N1 after some calls we are getting below error

23/12/18 06:15:44 000002M|019/00/0/004|=3:4101=Maximum number of trunks on an acces 19-0-0 is overflown
23/12/18 06:15:44 000002M|---/--/-/---|=2:1662=Monitel: Lack of resource for ISDN processing, type 1, access no 54.

During this time there we are not able to call any user from N2 to N1 but N1 to N2 call is happening at the same time N2 to N3 call is also happening.

During this time There are free trunk ports in all the ABC-F trunk group and there are enough compressor resources.

Have tried increasing the trunk circuits in ABC-F TG for both N1 & N2 but issue still persists.

Request help.
Attaching vpn configurations created in N1 & N2.
