Calling number not recognized in Zoiper phonebook because /-()

Question

We are having Phone-Contacts in Zoiper contacts like this:

Mr. Miller

0911/1234567-982

This is to distinguish local-prefix (0911) and leading number of the company (1234567) and extension (982). 

When calling out everything ist fine, when Mr. Miller calls _in_ he comes like this

09111234567982

Zoiper does not recognize the number from my zoiper phonebook.

Comments

Hello,

With Zoipe 5.2.25+ such issue should not exist, I believe.
