A new trunking arrangement has been installed between HamShack HotLine and MeshPhone.
This arrangement lets a user on one network directly call a user on the other network without going through any intermediate steps.

MeshPhone -> HH
1. Dial 78, wait for dial tone then dial the HH extension as follows:

1. If the HH extension is 3-digits long, dial 590-0xxx from MeshPhone where xxx is the 3-digit HH extension number.
   For example, HH extension 456 is MeshPhone 590-0456
2. If the HH extension is 4-digits long, dial 590-xxxx from MeshPhone where xxxx is the 4-digit HH extension number.
   For example, HH extension 4508 is MeshPhone 590-4508
3. If the HH extension is 5-digits long, dial 59x-xxxx from MeshPhone where x-xxxx is the 5-digit HH extension number.
   For example, HH extension 50223 is MeshPhone 595-0223.

HH 10-digit extension numbers are not supported from MeshPhone at this time.


HH -> MeshPhone
Dial 88 plus the MeshPhone 7-digit number.
For example, MeshPhone extension 973-2111 is HH 88-973-2111 (do not wait for a second dial tone)

73, Mark, N2MH
MeshPhone: 973-2111
HH: 88-973-2111
