Senerio - System A BCM400 with Sip trunks and 85 phones. 83 can 4 digit dial anywhere in the network using the sip trunks. Two phones cannot dial one site 31XX, as soon as 4th digit is dialed we get reorder tone. Created access code for that pool and those two phones can dial XX 31XX no problem. If you remove the name from the extension it can dial 31XX, however the other 83 phones have a name on the ext. All routing and dest codes are correct we have tried different phones and ports with no difference. Has anyone seen this before.
